Product description: Power Management Hat (B) - power management module - shield for Raspberry Pi - Waveshare 23452
Power Management Hat (B) is an overlay designed for the Raspberry Pi board that allows you to manage energy . The overlay is equipped with a dual-core RP2040 processor with a clock frequency of up to 133 MHz, which is responsible for controlling the operation of the device. It allows the user many useful functions, such as: timed switching on and off or measurement of operating voltage and current consumption. The Power Management Hat (B) is also equipped with the MP28167-A buck-boost chip for fast response to load transients.
Product compatible with Raspberry Pi 4B!
