PS5 DualSense Controller BDM Revisions: The Complete Guide (BDM-010 to BDM-060)

By Epoch Ctrllrs last updated: April 15, 2026

Since the PlayStation 5 launched in November 2020, Sony has quietly released six hardware revisions of the DualSense controller. Every single one ships under the same external model number and looks identical from the outside, but internally they’re different beasts. If you’re repairing controllers, modding them, or just trying to buy the right replacement parts, understanding these revisions is essential.

Sony doesn’t publish release notes for controller hardware changes. Everything we know comes from teardowns by the repair and modding community. This guide consolidates that knowledge into one place.

How to Identify Your DualSense BDM Revision

There are three ways to identify the BDM revision of a DualSense controller, depending on whether you have it connected to a PC, in-hand but unopened, or already disassembled.

1. Via the DualSense Controller Tester (most reliable)

The most direct method is the browser-based tester at ds.daidr.me. Connect the controller to a PC via USB, open the tool, and navigate to the Factory Info section. The Board Version field will display the BDM revision exactly - for example, BDM-020 - along with a wealth of other factory data including firmware versions, serial number, battery barcode, and motor info. This reads directly from the controller’s firmware and is unambiguous.

2. Via the serial number (no tools needed)

The serial number is printed on the back of the controller, usually found beneath the QR code near the “Made in China” text. It’s a 17-character alphanumeric string.

The second digit of the serial number indicates the version: 1 = V1 (BDM-010), 2 = V2 (BDM-020), and so on up to 6 = V6 (BDM-060).

For example, a serial number starting with F21800... is a V2 controller, because the second digit is 2.

Note: the serial number on the back matches the Serial Number field shown in the ds.daidr.me Factory Info panel, so you can cross-reference both.

3. On the motherboard PCB (requires disassembly)

Once the controller is open, the BDM revision is printed directly on the motherboard PCB. This is the definitive source - but obviously requires cracking the controller open first, so it’s most useful when you’re already inside for a repair.

The Six Revisions at a Glance

Note that V1 through V5 all share the same external model number (CFI-ZCT1W). The V6 / BDM-060 is the first revision to get a new model number: CFI-ZCT2W. This is sometimes referred to as the “DualSense V2” in the community.

BDM-010 (V1) - The Original

The launch DualSense shipped with every PS5 in November 2020. It introduced the revolutionary haptic feedback and adaptive trigger system that made the DualSense a generational leap over the DualShock 4.

Internally, V1 controllers are the most distinct from everything that followed. The shell mouldings differ slightly from V2 onwards, which means newer aftermarket shells don’t fit V1 controllers cleanly - they’ll leave visible seams along the edges. The adaptive trigger mechanisms in V1 were fully modular, making them relatively straightforward to service or replace.

The V1 uses the LIP1708 battery pack (3.65V, 1560mAh). All DualSense controllers share the same battery capacity, but the actual battery model number alternates across revisions.

The V1 touchpad PCB uses an 18-pin FPC connector - unique to BDM-010. It also comes in two sub-variants based on the size of the touchpad controller IC: a large IC (5mm wide) and a small IC (4mm wide). These sub-variants are not interchangeable with each other, and the replacement touchpad PCB must match the IC size on the motherboard. When sourcing replacement touchpad boards for BDM-010 controllers, you need to specify both the revision (010) and the IC size - sellers on AliExpress and parts sites will often list them as separate SKUs.

The BDM-010 is the revision most commonly found in second-hand bundles and used controller lots, as it shipped with every original PS5 console.

BDM-020 (V2) - The First Refinement

Sony’s first internal revision arrived silently in 2021. Externally identical to the V1, the BDM-020 introduced subtle changes to the motherboard layout and some minor refinements to the adaptive trigger springs. Some teardown experts noted that the trigger springs were slightly thicker (approximately 0.3mm versus 0.25mm in the BDM-010), suggesting Sony was already trying to address durability concerns.

One easy way to distinguish a BDM-010 from a BDM-020 without opening it: look at the back of the controller. BDM-020 units have a small letter “A” in the middle of the top lines of regulatory text. If there’s no letter A, it’s a BDM-010.

The V2 switched to the SNYHR37 battery pack. Same capacity, different model number.

The BDM-020 touchpad PCB moved to a 16-pin FPC connector, down from 18 pins on the BDM-010. Critically, the large IC / small IC sub-variant split carries over - BDM-020 touchpad boards also come in a 5mm (large IC) and 4mm (small IC) variant, and they remain non-interchangeable. As with the BDM-010, you need to confirm both the revision and the IC size before ordering a replacement. The BDM-010 and BDM-020 touchpad PCBs are not cross-compatible with each other.

Importantly for repair and modding purposes, the BDM-010 and BDM-020 share essentially the same external shell dimensions. Aftermarket shells designed for one will fit the other.

BDM-030 (V3) - Trigger Overhaul

The BDM-030 brought the most significant internal change up to that point: a redesign of the adaptive trigger mechanism housing. The trigger assembly shifted from the modular design used in V1 and V2 to a more integrated approach, with different screw positions and a different internal housing shape.

This is the revision where shell and trigger compatibility starts to diverge from the earlier controllers. While the external shell dimensions remain very close to the V2, the internal trigger housings are different enough that V1/V2 trigger kits and “clicky” trigger mods from manufacturers like eXtremeRate will not fit a BDM-030. Face button kits, d-pads, and the outer shell itself generally remained compatible.

The V3 went back to the LIP1708 battery. The trigger springs are visible from the top when the triggers are pulled back, which provides another external identification method.

The BDM-030 introduced a distinct touchpad PCB that is not compatible with BDM-010 or BDM-020 boards. It retains the 16-pin FPC connector from the BDM-020, and the large IC / small IC sub-variant split is present in this revision too. The sensor pattern underneath the touchpad surface is a square wave design - the first time this pattern appears in the DualSense family.

BDM-040 (V4) - Slimming Down

The BDM-040 appeared in late 2023 and brought further refinements. At 274g, it’s 4g lighter than the V1-V3 controllers - a small change, but one that confirms internal material or design changes.

The good news for the repair community: Killscreen’s testing confirmed that all standard BDM-030 parts were interchangeable with the BDM-040. This includes triggers, bumpers, d-pad, face buttons, and the outer shell. The BDM-040 received a new FCC ID (AK8CFIZCT1B), but from a parts compatibility perspective, BDM-030 and BDM-040 are essentially the same.

The touchpad uses an alternating square wave sensor pattern, identical to the BDM-030. When comparing the two touchpad PCBs side by side, the only differences are some slightly different printed markings - they are functionally the same part and are interchangeable. The PCB layout changed, as it does with every revision, but user-facing functionality remains identical.

The V4 uses the SNYHR37 battery.

BDM-050 (V5) - Incremental Polish

Arriving in mid-August 2024, the BDM-050 is another iterative refinement. The most notable change is the touchpad: the sensor pattern switches from the square wave design used in BDM-030 and BDM-040 to a new honeycomb pattern. This is a genuine hardware difference - the BDM-050 touchpad PCB is not interchangeable with the square-wave touchpads from BDM-030 or BDM-040. Some PCB components were rearranged, and the motherboard now features sub-variants (BDM-050M, BDM-050R) that may indicate different production batches.

One change worth noting for modders: Sony switched from a metal hinge pin on the trigger mechanism to a plastic one. This isn’t unprecedented - the DualShock used plastic hinges too - but it’s a materials change that the community is watching for long-term durability implications.

The BDM-050 shares the same FCC ID as the BDM-040 (AK8CFIZCT1B). eXtremeRate confirmed that face button clicky kits and LED kits work with the BDM-050, though clicky trigger kits may need minor adjustments.

All DualSense controllers through V5 still use ALPS potentiometer-based joystick modules, which remain susceptible to stick drift.

The V5 uses the SNYHR37 battery.

BDM-060 (V6) - The “DualSense V2”

The most significant revision to date. The BDM-060 began appearing in late 2025, bundled with PS5 Pro consoles (CFI-7121), the latest PS5 Slim (CFI-2116), and special edition controllers like the Icon Blue and Ghost of Yōtei Gold editions.

This is the first revision to receive a new external model number: CFI-ZCT2W. The changes are substantial. Sony redesigned the circuit board entirely, introducing a MediaTek low-power Bluetooth chipset, a physically smaller main processor, and removing the secondary rear microphone. The result is dramatically improved battery life - independent testing by Polish modder Modyfikator89 showed over 15 hours of continuous play with all features active, compared to the 6-10 hours typical of earlier revisions. This was achieved without increasing the battery capacity, which remains at 1560mAh.

Critically for the repair and modding community, eXtremeRate has confirmed that the BDM-060 may cause compatibility issues with some existing mod kits. Testing is ongoing, so check with your parts supplier before ordering.

The BDM-060 still uses ALPS potentiometer-based joystick modules. Sony has not adopted Hall Effect or TMR stick technology in any DualSense revision to date.

You can identify a BDM-060 by the CFI-ZCT2W marking on the controller packaging.

Shell Compatibility Matrix

This is where things get practical. If you’re buying replacement shells, you need to know what fits what. Here’s the compatibility breakdown based on community testing and manufacturer data:

The key takeaway: shells fall into two main groups. Group A covers BDM-010 and BDM-020. Group B covers BDM-030 through BDM-050. The BDM-020 sits on the boundary - some Group B front shells will fit but may leave larger seams. The BDM-060 is too new for definitive compatibility data.

When buying aftermarket shells from eXtremeRate, Alibaba suppliers, or others, always check their listed BDM compatibility. eXtremeRate’s “Luna Redesigned” full shell sets, for example, are specifically listed for BDM-030/040/050 as one SKU, and BDM-010/020 as a separate SKU.

Button and Trigger Compatibility

*The BDM-050 switched from a metal to plastic trigger hinge pin, which may affect fit of some aftermarket trigger kits.

The pattern is clear: face buttons, d-pads, thumbstick caps, and L1/R1 bumpers are safe bets across all revisions. L2/R2 triggers and the adaptive trigger mechanisms are the compatibility headache, splitting cleanly between V1-V2 (Gen 1) and V3+ (Gen 2). The touchpad PCB is version-specific and - on BDM-010 through BDM-040 - IC-size-specific within each revision. See the Touchpad Compatibility section above for the full breakdown.

Battery Compatibility

Both battery models share the same specifications (3.65V, 1560mAh, 5.7Wh) and are functionally interchangeable across all revisions. The different model numbers reflect sourcing or manufacturing changes rather than performance differences.

The BDM-060’s dramatic battery life improvement (6-10 hours to 15+ hours) was achieved entirely through more efficient electronics, not a larger battery.

Touchpad Compatibility

The touchpad is one of the most misunderstood parts to source for DualSense repairs, because compatibility breaks down across multiple axes simultaneously: the BDM revision, and - for earlier revisions - the IC chip size on the touchpad PCB.

The IC size sub-variant problem is what catches people out most often. On BDM-010, BDM-020, BDM-030, and BDM-040 controllers, there are two versions of the touchpad PCB for each revision - one with a large touchpad controller IC (5mm wide) and one with a small IC (4mm wide). The IC size on the replacement touchpad must match the IC size on the motherboard. They look almost identical from the outside; to confirm which you have, either measure the IC chip width directly or compare against reference photos from parts suppliers. Suppliers like Kasynparts and Egamephone list them as separate product listings (e.g. “BDM-010 large IC” vs “BDM-010 small IC”).

The connector change between BDM-010 and BDM-020 is a hard incompatibility. The BDM-010 uses an 18-pin FPC ribbon cable to connect the touchpad to the motherboard; all subsequent revisions use a 16-pin cable. You cannot fit a BDM-020 touchpad PCB into a BDM-010 controller, and vice versa.

The BDM-030 and BDM-040 touchpad PCBs are interchangeable with each other (matching IC sizes), and represent the most widely available replacement parts. If you’re stocking spares for repair work, BDM-030/040 touchpads give you the broadest coverage.

The BDM-050 honeycomb touchpad is a standalone part - it does not cross-fit with the square-wave PCBs from BDM-030/040, despite using the same 16-pin connector.

Stick Drift Across Revisions

Every single DualSense revision from BDM-010 through BDM-060 uses ALPS potentiometer-based joystick modules. Sony has not adopted contactless sensing technology (Hall Effect or TMR) in any standard DualSense revision.

This means stick drift remains a hardware inevitability across all versions. The potentiometer mechanism relies on a metal wiper making physical contact with a carbon track. Friction causes wear, the signal degrades, and drift develops - typically after around 300 hours of use, though this varies significantly with playstyle.

For a permanent fix, the joystick modules can be replaced with TMR (Tunnel Magnetoresistance) or Hall Effect modules. These use magnetic sensing instead of physical contact, eliminating the root cause of drift entirely. This repair requires desoldering the original module and soldering in the replacement - an intermediate-level soldering job that takes roughly 45 minutes per controller.

What This Means for Repair and Resale

If you’re buying used DualSense controllers for repair and resale, here’s the practical takeaway:

The safest shell strategy is to buy “full set” shells that include all buttons, triggers, and housing as a complete kit matched to the correct BDM group. This avoids the compatibility lottery of mixing parts across revisions. eXtremeRate and various Alibaba suppliers sell these as complete kits in two main SKUs: one for BDM-010/020, another for BDM-030/040/050.

The safest button strategy is to stick with face buttons, d-pads, and thumbstick caps, which are universally compatible. Avoid trigger-only kits unless you’re certain of the target BDM revision.

Touchpad PCBs require the most care when sourcing. You need to know the BDM revision and the IC chip size (large 5mm or small 4mm) for controllers up to BDM-040. Open the controller, identify the IC on the motherboard, and measure or compare before ordering. BDM-030/040 touchpads represent the best parts to hold in stock - they cover two revisions and are widely available. Keep BDM-010 and BDM-050 touchpads separate, as neither crosses over.

The TMR joystick upgrade works across all revisions. The joystick module footprint is standardised, so a TMR swap is BDM-agnostic - it’s the one repair you can stock parts for without worrying about version compatibility.

Identify before you buy. If you’re buying controllers in bulk for repair, ask sellers for serial number photos or check them immediately on arrival. Knowing your BDM mix informs your parts ordering.
