The Pico-UPS-B is a dedicated UPS (Uninterruptible Power Supply) module designed for Raspberry Pi Pico. It incorporates a Li-po battery switching charger with power path management, and a voltage/current monitoring chip that allows monitoring the battery operating status via the I2C bus. What's more, the male pin header makes it possible to "stack" other modules on top.
- Standard Raspberry Pi Pico header supports Raspberry Pi Pico series boards
- Incorporates Li-po 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, more safe and stable
- Onboard recharging indicator, power indicator, easy to check the battery status
- Recharge voltage: 5V
- Control bus: I2C
- Battery support: 600mAh 3.7V Li-po battery
- Dimensions: 60 × 21mm
You can refer to the guides of Raspberry Pi: https://www.raspberrypi.org/documentation/rp2040/getting-started/
- 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
- 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
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
