X1200-v1.2 Hardware & Installation

Hardware Description



Raspberry Pi GPIO Used

PIN# | GPIO | Functions

3 | GPIO2 | I2C-SDA, battery fuel-gauge systems - reading battery voltage and percentage
5 | GPIO3 | I2C-SCL, battery fuel-gauge systems - reading battery voltage and percentage
31 | GPIO6 | AC power loss & power adapter failure detection, Low-power supply failed, High-power supply OK
36 | GPIO16 | Control battery charging, High-charging disabled, Low-charging enabled

*The UPS connects to the Pi GPIO via pogo pins. If the I2C address (0x36) is not detected or fails to read AC power state or control charging, please ensure to clear the leads of the pins used on the GPIO header from the bottom of the Raspberry Pi PCB and then reinstall it.

Battery Voltage Level Indicators

Battery Voltage Range (V) | D1 | D2 | D3 | D4 | Remark
