Interlink Electronics PCB 10‑45469 is a compact MicroModule “mouse” joystick board that provides 360° directional and speed control via finger pressure; it is typically mounted in industrial handheld or rugged computers. Common failures on this model include cracked flex cable leads, burned-out microcontroller ICs, degraded capacitors on the power supply section, and loss of signal from the pressure sensor due to mechanical wear. Initial checks should verify that the board receives its rated input voltage (typically 5 V) with a stable rail, inspect all surface‑mount components for visual damage or corrosion, and confirm that the joystick return spring and flex cable are intact; then read any onboard diagnostic LEDs or error codes if present.[oss-gpt-20b]
