Raspberry Pi Zero UPS HAT expansion board (19739)

TheRaspberry Pi Zero UPS HAT (19739 ) is designed to provide uninterrupted power to the Raspberry Pi Zero microcomputer when the USB cable is disconnected. It automatically switches the microcomputer's power to the rechargeable battery, so that the device does not notice a power outage via the adapter or USB interface.

This board is designed specifically for use with the Raspberry Pi Zero (W, WH) series. The spring-loaded 6-pin Pogo connector provides reliable contact with the microcomputer's pins, while all GPIO pins remain free for use in other circuits.

The board has a built-in battery status monitoring function that displays the voltage (V), current (A), power (W) and remaining battery charge (in%) in real time (via I2C), which allows you to plan charge consumption and disconnect the microcomputer in advance if it is not possible to plug it into the network for recharging. A negative current value(Current) corresponds to the battery discharge mode

Main features:

• Built-in spring pins for connection to Raspberry Pi Zero series boards
• Li-po battery recharge chip with dynamic charge curve control
• A voltage boost chip that provides adjustable output power at 5 V
• I2C communication, real-time monitoring of battery voltage, current, power and capacity
• Multiple battery protection circuits: overcharge/discharge protection, overcurrent protection and short circuit protection
• Charging indicator to monitor battery health
• Supplied with development resources and manual
