BFKK X735 V3.0 Power Management Board for Raspberry Pi

SKU CH-W53D-EWYW4

Expansion board adds safe power management, software shutdown and temperature-controlled fan to Raspberry Pi 40-pin models

  • Wide 6–30 V input powers Pi from many sources
  • On-board button enables power on, reboot and safe shutdown
  • Software-controlled full power-off protects data integrity
  • Automatic PWM fan adjusts speed to temperature for thermal safety
  • Stackable 40-pin header allows adding other HATs on top

Power Management for Raspberry Pi

The BFKK X735 V3.0 board adds intelligent power control to Raspberry Pi models with a 40-pin header. It accepts 6–30 V input through a DC jack, Type-C, Micro-USB or XH2.54 connector. An on-board button handles power-on, reboot and safe shutdown, while software-triggered full power-off protects the SD card. The board also feeds external devices via the XH2.54 socket and the stacked header.

Installation and Common Issues

Mount the board on the 40-pin header using the supplied M2.5 screws, copper pillars and acrylic panel. Connect your chosen power source and attach the PWM fan to the dedicated header. Configure temperature thresholds and fan curves through the provided software interface. A frequent issue is an incorrect safe-shutdown script on non-official operating systems; verify the script runs before relying on automatic power-off.

Pre-Order Checks

Confirm your Raspberry Pi uses the standard 40-pin GPIO header and runs Raspberry Pi OS for guaranteed safe-shutdown support. Ensure your power supply delivers within the 6–30 V range and uses a compatible plug type. Check that case clearance accommodates the stacked board, acrylic panel and fan assembly. Verify whether other HATs you plan to stack share any GPIO pins used by the fan or power-control circuitry.

Questions about this item

How can I verify the X735 V3.0 board is managing power correctly after installation?

The on-board button controls power on, reboot and safe shutdown; when pressed it triggers a full power-off sequence that is confirmed by the Raspberry Pi OS safe shutdown routine.

What comes in the package and what must I source separately to use the board?

Included are the X735 V3.0 board, eight M2.5×5 mm screws, four double-pass copper pillars, four copper pillars, a jumper link and an acrylic panel; you must provide a Raspberry Pi with a 40-pin header and a 6–30 V power source.

Which version of the X735 board should I choose for a Raspberry Pi 4B?

The V3.0 revision supports all current Raspberry Pi models using the 40-pin header, including the 4B, 3B and 2B, so this single version covers those boards.
