Power Management HAT(B) is a Raspberry Pi power management control board, which can provide a set of extremely powerful power management for Raspberry Pi, such as timing switches, measuring working voltage and current, etc. The load transient response function enables fast switching among multiple power supplies. 

Featuring an RP2040 MCU on board which can be programmed to efficiently schedule power on-off to the PI board. Not only that it can switch the power source from main source to backup battery source. That's not all, this HAT also provides the UPS functionality to the Raspberry Pi Board. When added with a suitable battery, this HAT can provide backup power to the system when the main source fails suddenly due to any unforeseen circumstances.
