The Waveshare 19739 UPS HAT (C) For Raspberry Pi Zero is a 5V Uninterruptible Power Supply allows you to power your Pi Zero seamlessly from power connection or backup batteries.
Features:
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
- Comes with development resources and manual
| OUTPUT VOLTAGE | 5V | CHARGER | 5V |
|---|---|---|---|
| CONTROL BUS | I2C | BATTERY | 803040 Li-po battery 1000mAh 3.7V |
| MOUNTING HOLE SIZE | 3.0mm | DIMENSIONS | 65 × 30mm |
It is able to recharge the battery and provide power output at the same time from external power supply.
Automatically switch over to battery output if external power supply is unavailable, keeps the system running without any trouble.
Bottom Pogo Pin Connection, Allows Attaching Other HATs On The Top
Monitoring The Battery Voltage, Current, Power, And Remaining Capacity Via I2C
