The Flex Test Board Micro-USB and Type-C Battery Power Charging Dock Module for Android Phones. Easy to use—connect directly to the phone’s charging port. Enables testing without powering on the device. Designed for testing U2 IC, battery, and charging port functionality. Eliminates the need to disassemble phone components—simply plug the test board into the phone’s charging port. Compatible with both Type-C and Micro-USB Android devices. Applications: 1. U2 IC Testing 2. Battery Testing 3. Charging Port Testing Pin Definitions (when test board is face down): 1 – Identification / Control 2 – Channel 1 Negative 3 – Channel 1 Positive 4 – Power / Battery 5 – Identification / Control 6 – Channel 0 Negative 7 – Channel 0 Positive 8 – Ground Testing Instructions: - For U2 IC and battery testing: Use multimeter in diode mode; swap red and black probes to measure values. - For charging port testing: Use multimeter in diode mode; swap red and black probes to measure values. Note: Due to potential pin probe misalignment, it is recommended to first measure and record readings from a known-working phone for reference when diagnosing faulty units.
