Product Introduction

As everyone at some point recognize that the Raspberry Pi downside is the fact that it’s missing any kind of a power button. The only way to power the Raspberry board off is by unplugging it from the power supply. What can sometimes corrupt data stored on the SD card if device is suddenly being powered off during operation. To solve this problem, 52Pi company came out with a smart solution in a form of a special expansion board , that connects to the raspberry 40 GPIO pin header and the lets you turn on/off the Pi board remotely via IR remote control unit and the expansion board power button.

When you power the Raspberry with this expansion board it doesn’t only power it off, but also send a signal to the board and give few seconds delay to initialize a proper shutdown to the Pi Board, what assures that stored data is not damaged in any way.

This power expansion board could be very particle for hobbyist that use the Raspberry Pi boards as a type of a home media player center, to stream content from the internet, or just users that need to have the remote option for specific DIY projects, For example when designing Alarm systems, Smart home solutions.

The Power Button provides a small circuit that includes the following features:

  • Sending a shutdown signal to the Raspberry if the Shutdown Button is pressed
  • Time delay function – waiting for the Raspberry to shut down
  • Powering off the Raspberry after saving data
  • Powering on the Raspberry after the Button is pressed again
  • LED light indicating the current state: On / Shutdown / Off
  • Dimension: 65 mm x 30 mm x 20 mm
  • Easy to setup


Package Contents :

  • 1x Switch Remote Control Module
  • 1x IR Remote controller.




Unpacking all Items

  • 1x Switch Remote Control Module
  • 1x IR Remote controller (Battery not included)

Accessories supplied

52Pi power switch expansion board came with a simple ON/OFF IR remote control unit in decent quality. Cables for operating this board are not needed because the power is provided using the Pi power adapter via the power switch Micro USB interface. Controlling the Pi board on/off modes is completely done using the GPIO interface pins. Also important to mention that package does not include a battery necessary for the remote control unit, therefore you will need to buy a 3V cr2025 lithium battery.

a closer look at the Board

As explained in product intro, The Pi boards don’t have any onboard power button. The power switch expansion board provides two powering methods. It comes with onboard power button that lets you to manually switch the Pi board on & off. The second option, with on-board IR Receiver that lets you power the unit remotely via a basic IR remote control equipped with a simple ON/OFF button.

52Pi Power Switch Expansion Board


 – Configuration #1 –

Raspberry Pi 3 + Power Switch Card


 – Configuration #2 –

Raspberry Pi 3 + Power Switch Card + 7 Port Self Powered USB Hub


Hardware Compatibility

The power switch expansion board is compatible with Raspberry Pi 2, 3 and the Zero series boards. Banana Pi and Orange Pi brand boards based on All Winner SoC maybe also work with it, but I can’t guarantee %100 compatibility because it likely depends on the GPIO pin arrangement on the specific board.

It can be a great solution for home media player and KODI fans that would want to use a remote control with their PI boards, instead of powering the Pi board on and off each time by unplugging the Pi power adapter cable by hand or using a power socket with built-in switch. Also, hobbyists using the Pi as a type of a workstation and server applications can benefit from having a proper system shutdown.


Operation & Setup

Setting up the board to work with a Raspberry Pi 2, 3 board:

  • Step #1: Hooking the Board it into the Pi 40 GPIO pins interface.
  • Step #2: Modifying the OS Image config file:  /boot/config.txt


Adding the following lines:



Modifying Config.txt file (Example)


  • Step #3: Installing ‘wiringPi’ GPIO library & moving script file to  /etc/init.d/


Step # 4: Editing the rc.local file and adding the following lines:


Note: The setup Instructions also can be found in 52Pi Product wiki page Here


Final Verdict (Pros / Cons)

52Pi Power Switch is a very nice addition to the Pi boards, including other SBC that would like to power their boards remotely via a remote control unit. The only disadvantage I found with this product, is that it occupies the Pi GPIO pins, so for developers that really need access to the pins, will find that they are limited and can’t use both.

That said, this board is a nice and cheap solution when there is a need to turn the Pi board completely in an organized way, without damaging files during device operation. Overall, I think it’s a must have product.



  • Works Well
  • Cheap
  • Easy to setup



  • Occupies GPIO interface.
