LORDWORLD Power Management HAT for Raspberry Pi development board

SKU CH-AJE9-MKHEC

Adds real-time clock, buck-boost power and voltage monitoring to a Raspberry Pi

  • Precise timekeeping via onboard PCF8523 RTC chip
  • Fast load response with MP28167-A buck-boost DC chip
  • Custom power control through user-defined button
  • Safe operation ensured by anti-reverse and counter-current protection
  • Real-time voltage and current monitoring for Raspberry Pi

Power Management HAT for Raspberry Pi

This HAT adds regulated power control and a real-time clock to a Raspberry Pi development board. It includes a dual-core Arm Cortex M0+ processor running up to 133 MHz for power sequencing tasks. The onboard PCF8523 RTC maintains accurate timekeeping when the main board is off. Builders who need uninterrupted uptime and safe power transitions will find it useful. Buyers who want more storage or wireless connectivity must look elsewhere.

Compatibility check before ordering

Verify that your Raspberry Pi model has a standard 40-pin GPIO header and supports HAT mounting. The board draws power through the GPIO connector, so confirm your power supply can deliver sufficient current for both the Pi and attached peripherals. No specific voltage or current ratings are provided in the specifications. Ensure your enclosure allows access to the user-defined button and any exposed headers.

Build quality and daily use

The MP28167-A buck-boost DC chip handles fast load transients while protection circuits guard against reverse polarity and reverse current. A monitoring circuit reports operating voltage and current in real time. The user-defined button can trigger startup, safe shutdown, or custom scripts. Connectors follow the standard HAT layout, so the board stacks directly on the GPIO header without extra cables.

Questions about this item

What comes in the box with the LORDWORLD Power Management HAT and do I need to buy anything extra?

The HAT board itself is supplied; a compatible Raspberry Pi board, a power source and any mounting hardware are not included and must be sourced separately.

Which version or capacity of the LORDWORLD Power Management HAT should I choose?

Only one hardware variant is offered — the board with the dual-core Arm Cortex M0+ processor running up to 133 MHz, PCF8523 RTC, MP28167-A buck-boost chip, user button and protection circuits.

What does the 133 MHz clock speed mean when the HAT is running on a real Raspberry Pi?

The dual-core Arm Cortex M0+ processor can execute its power-management firmware at up to 133 MHz, enabling fast load-transient response from the MP28167-A buck-boost chip and real-time voltage/current monitoring while the Pi is operating.
