Jdm-040 Schematic Direct

Looking at the connector with the board oriented vertically (connector at the bottom):

If the controller fails to charge, the Power Management IC (PMIC) may be faulty. Some modders use an alternative TP4056 charging module as a workaround if the original IC is irreparable. jdm-040 schematic

Each joystick uses two potentiometers (X and Y axis). The schematic reveals the voltage dividers that send signals to the MCU. Carbon track wear causing "stick drift." Looking at the connector with the board oriented
