Report Item
* for reference ONLY, the Raspberry Pi Zero, display module, and MicroSD card are NOT included.
When using the battery, please pay attention to the following two points:
Note 1: When assembling, make sure to switch the power to the OFF position first. Disconnect the power before assembling; otherwise, it may cause a short circuit and damage the components.
Note 2: When connecting the battery for the first time, you need to charge it through the USB port to activate the battery protection chip; only then will there be power output.

Power your Pi Zero seamlessly from power connection OR the backup batteries
Supports Recharging and regulated 5V output at the same time, I2C monitoring
The UPS HAT (C) is an uninterruptible power supply module specialized for Raspberry Pi Zero series. It incorporates Li-po battery switching charger with path management, voltage boost chip, and voltage/current monitor which allows monitoring the battery operating status via I2C bus.
Onboard spring pogo pins for connecting with Raspberry Pi Zero series boards
Li-po battery recharge chip, with dynamic path management, more stable power supply
Voltage boost chip, providing regulated 5V power output
I2C bus communication, monitoring the battery voltage, current, power, and remaining capacity in real time
Multi battery protection circuits: over charge/discharge protection, over current protection, and short circuit protection, more safe and stable
Recharging indicator for monitoring the battery operating status
