The Pico-UPS-A is a dedicated UPS (Uninterruptible Power Supply) module designed for Raspberry Pi Pico. It incorporates a Li-ion battery switching charger with power path management, and a voltage/current monitoring chip, which allows monitoring of the battery operating status via the I2C bus.
- Standard Raspberry Pi Pico header supports Raspberry Pi Pico series boards
- Incorporates Li-ion battery switching charger with dynamic power path management, more stable power supply
- 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, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable
- Onboard recharging indicator, power indicator, and battery warning indicator to check if the battery is connected correctly
- Recharge voltage: 5V
- Control bus: I2C
- Battery support: 14500 battery (Not included)
- Dimensions: 60 x 21mm

Working with Raspberry Pi
- Access Raspberry Pi and open the terminal
- Download the download and unzip it to the Pico C/C++ directory. You need to follow the guides of Raspberry Pi to install SDK first.
wget -P ~/pico https://www.waveshare.com/w/upload/9/92/Pico-UPS-A.zip cd ~/pico unzip Pico-UPS-A.zip
- Press the BOOTSEL button of Pico and connect the Pico to your Raspberry Pi by USB cable and then release it.
- Build and run the C examples
cd ~/pico/Pico-UPS-A/c/build/ cmake .. make sudo mount /dev/sda1 /mnt && sudo cp Pico_UPS.uf2 /mnt && sudo sync && sudo umount /mnt && sleep 2 && sudo minicom -b 115200 -o -D /dev/ttyACM0
- The expected result should be as figure below:
- Access Raspberry Pi and open the Thonny.
- Open the example by the IDE and save
- Click the Run button to run the codes
