This product is an UPS uninterruptible power supply expansion board for Raspberry Pi Pico , working with 18650 lithium battery, which can be identified the working status of the UPS board through different LED displays. There are "charging mode", "discharge mode", and "warning mode for battery reverse connection ". This UPS board also has an independent power supply, which can realize charging while discharging or only charging. The board features a battery detection function. When the battery is reversed, the alarm warning light is on, and the UPS board does not work. We provide demo codes of C and python that can detect voltage, current, power and electricity.
