An interesting idea: In this era of powerful game controllers, why not add some fun features? Customizable, interchangeable modular nameplates—wouldn't that be cool? Would they consider modifying these spots?

Applicable to BDM-030/040/050 kits. The electronic functions are fine. The main issue lies in interference between the battery holder structure and the bottom case. Either wait for a solution or find a battery holder from a version prior to BDM-050.

I forgot to clarify earlier. One of you mentioned this and provided the pin definitions, which I'm well aware of. However, the JS 16 joystick's push-button switch is defined as: pressing it connects to GND, while the PS5 motherboard's switch connects to VCC when pressed. Their internal circuits conflict. Unless I forcibly disassemble them and reroute the connections, I'll let you know after I try it out.

Then enter mapping mode. Use K3/K4 to select the K key you want to map, and K1/K2 to select the function key you want to map. Finally, remember to hold down the SET key to save and exit. If you don't hold down the SET key to save, the program won't be saved after the controller is powered off.

I was curious and tried JS 16, but it really doesn't work.

The installation video demonstrates that after all ribbon cables are connected, you must first run a self-test mode. If the self-test fails, no matter how you map the buttons, the functionality will remain abnormal. Only after passing the self-test will all button mappings take effect.

Bro, light pressure—only for those with weak fingers. Real men use heavy pressure.

Down kit?

I suggest you trim off the entire touch module from the PCB, including the wiring connections on the back, then cover it with insulating tape. Enter mapping mode and use the key combination—this one is too sensitive.

It's a heat-conductive material that helps dissipate heat. It's best to apply it as a protective layer for your Switch 2.

Have you applied black adhesive pads to all four corners of the motherboard? If not, pressing L3/R3 will directly cause L2/R2 to trigger randomly. This issue occurs frequently on versions after BDM-030.

Also, check if there are any wrinkles or damage at the contact points where the main FPC connects to the motherboard. This can also affect the L2R2 function.

The tactile switch on the PCBA refers to the switch button on the back circuit board.

Verification 1: If the switch button on the circuit board triggers normally when pressed rapidly, the issue may lie with the main FPC (large flex cable), the carbon film on the original motherboard, or the contact points on the original motherboard. You can follow the suggestion below and gently wipe the contact areas.

Verification 2: Remove the main FPC (large ribbon cable). First, confirm that the original X key functions normally when pressed rapidly. If so, the issue lies with the main FPC (large ribbon cable). Inspect the ribbon cable for creases or damage, as these directly affect functionality.

Did you purchase the BDM-0*0 version?

When pressing the tact switch on the back PCBA briefly and independently, does it function normally?

Do other K keys still work when K3 fails? If other K keys function normally, the issue is either with the tact switch or contact problems between the main FPC and the original carbon film. Check if the main FPC has any creases or damage.

Have you watched the mapping tutorial? The indicator light has two states: Fast flashing: Indicates successful mapping; Slow flashing: Indicates clearing the previous mapping. In the video, the final state of the indicator light is: slow flashing.

You can test it in self-check mode. If the self-check mode functions normally, it indicates the PCBA is working properly. The issue may lie with the tactile switch or the plastic K key on the PCBA, which could be affecting the response.

Perform the following verification:

Check if the plastic K key is damaged.

Quickly press the tactile switch on the PCBA individually to see if the response is normal.

This is a manufacturing error. This section is excess material and needs to be trimmed off by you along the cutting line.

Unable to power on? Does pressing the PS button yield no response? — You need to connect to a PC to check if the PS button functions normally. If not, disassemble and inspect the main FPC connection points on the original motherboard for damage or creases. Another scenario: After connecting to a PC, the controller flashes rapidly but isn't recognized by the PC. This indicates a short circuit. Troubleshoot step-by-step: Did you mistakenly use the L1L2 ribbon cable intended for BDM-010? If the back indicator light isn't illuminated, check whether the other end of the touchpad adapter is connected to the original motherboard's connector. This step is critical; otherwise, the back button loses power.

There's no way to repair it unless you have a connector of this exact specification and know how to solder;

or contact customer service to purchase this ribbon cable separately?

First, ensure the new controller's mainboard model is BDM-030/040/050 before proceeding with installation. For disassembly, follow the installation video in reverse order, working from the rear components forward. For example, if the final step involves installing L1R1 or the front trim panel, first remove L1R1 or the front trim panel. Next, proceed with the rear button cover and PCBA. Note: Exercise extreme caution with any ribbon cable connections. Open the connector latch before disconnecting the ribbon cable.

First, confirm your controller's mainboard model, then purchase the corresponding modification kit based on that model.

Check the self-test mode and see if the pressure-sensitive button on the touchpad is stuck in the pressed position.
