Zeiwohndc X1202 UPS Extension Module for RPi 5 — I2C Power Management

The Zeiwohndc X1202 provides an uninterruptible power solution for Raspberry Pi 5 with I2C communication for real-time monitoring. Over I2C it reads battery voltages, current, power, remaining capacity and other parameters so you can track the module's operating status continuously. The board preserves the GPIO port, keeping compatibility with other RPi accessory boards. Safety and charging: Built-in battery protection handles anti-overcharge, anti-over-discharge, over-current protection, short-circuit protection and reverse-connection protection. It supports rapid battery charging while maintaining stable and safe operation. Indicators and continuity: Four green LEDs show charging and discharging status; the module can charge and discharge simultaneously to deliver uninterrupted power. A blue LED shows power-on and shutdown status. Power input and conversion: High-efficiency step-down DCDC conversion accepts a wide input range of 6V-18V. Common power input uses a 5.5x2.1mm jack. A switching button lets you power on, perform a safe shutdown, or force shutdown. Battery and outputs: Supports 4 x 18650 batteries to supply up to 10 hours of continuous operation (depends on battery type and application). Output options include an XH2.54 connector and two USB ports providing 5V power output.
