Supports PMIC voltage adjustment for models TU KU BU NU AU CU DU CS601 CS602 CS603 RT6948 RT929 RT6936 SM4190 series. Easy connection with SCL, SDA, GND, and 3.3V for straightforward operation. DIP switch selection for identifying the corresponding PMIC chip ensures compatibility. Save button functionality allows users to retain adjusted settings for use. Requires module reset when switching between different PMICs to clear previous data. This voltage adjustment module is designed to facilitate the adjustment of VGH/VGL voltages for various PMIC models. Users can easily connect the necessary pins and select the appropriate DIP switch for their specific IC. After achieving the desired voltage settings, the save button allows for data retention, ensuring that adjustments are not lost. It is important to reset the module when switching to a different PMIC to avoid conflicts with previously saved data. For optimal performance, that 3.3V is sourced correctly from the circuit.
