: Using the schematic knowledge to solder tiny "remap" chips for additional back paddles.
Unlike the unified chip in the JDM-001, the JDM-040 uses a two-chip solution. The main processor is typically a chip labeled CXD90063GG . This manages Bluetooth 5.1, USB communication, and haptic feedback logic. The schematic shows that this chip operates on multiple power rails: 3.3V for I/O, 1.8V for core logic, and a 5V input from USB. jdm-040 schematic

Always disconnect the battery before probing live voltages on your JDM-040. The 5V rail can destroy the delicate BGA SoC if shorted incorrectly. 1.8V for core logic
