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 for monitoring the battery operating status via I2C bus. Note: The Raspberry Pi Pico and 14500 battery NOT included. You'll need a Raspberry Pi Pico with male headers soldered to connect the Pico-UPS-A to the Raspberry Pi Pico. Features * 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: overcharge/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 * Comes with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples) Specifications * Recharge Voltage: 5V * Control Bus: I2C * Battery Support: 14500 Li-ion battery (NOT included) * Data rate: 800Kbps(typ) * Dimension: 60 x 21mm What's On Board * 1) ETA6003 recharger chip * 2) INA219 voltage/current monitoring chip * 3) S8261 Li-ion battery protection chip * 4) FS8205 Li-ion battery protection MOS * 5) AO3400 reverse-proof MOS * 6) SI2305 counter current preventing MOS * 7) Rapsberry Pi Pico header for direct attaching to Raspberry Pi Pico * 8) Power switch * 9) Activate button activate the protection circuit after replacing battery\ * 10) 14500 battery holder Resources * Waveshare Wiki Pinout Package Contents * 1x UPS Module for Raspberry Pi Pico Raspberry Pi Pico and battery NOT included https://elecena.pl/product/22724139/ups-module-for-raspberry-pi-pico-14500 2023-03-07 https://elecena.pl/product/22724139/ups-module-for-raspberry-pi-pico-14500 2023-12-27 https://elecena.pl/product/22724139/ups-module-for-raspberry-pi-pico-14500 2024-09-19 https://elecena.pl/product/22724139/ups-module-for-raspberry-pi-pico-14500 2024-11-29 https://elecena.pl/product/22724139/ups-module-for-raspberry-pi-pico-14500 2024-11-30 https://elecena.pl/product/22724139/ups-module-for-raspberry-pi-pico-14500 2025-09-27 https://elecena.pl/product/22724139/ups-module-for-raspberry-pi-pico-14500 2025-11-28 https://elecena.pl/product/22724139/ups-module-for-raspberry-pi-pico-14500 2025-11-29
