PocketPi MK2


Lately I’ve been refining some of my projects and improving on them. The first PocketPi inspired the ZeroBootSystem while making that smaller I also made the PocketPi smaller and simpler in its design. Join me below to see how I achieved a smaller thinner PocketPi



  • Raspberry pi Zero W
  • 3.5″ waveshare clone screen
  • Pass through raspberry pi headers
  • Power bank board
  • 2500mAh lipo battery
  • Switch
  • Button
  • JST connector
  • Micro USB port
  • Custom PCB
  • Bluetooth keyboard
  • Mobile phone magnetic holders x2
  • 2.5M bolts x4
  • 2.5M male to female standoffs 12mm x2
  • 2.5M nuts x4

USB hub

  • Female USB port
  • Custom PCB

Acrylic mount

Like with the original PocketPi I attached all the hardware to a piece of clear acrylic but unlike the original PocketPi I only needed one piece. To attach the keyboard I used 2 of these mobile phone holders where you stick a metal disk to back of your phone then mount the magnetic part to your cars dash, Because I used 2 of these mounts this time I didn’t need anything to keep the keyboard in place unlike last time.

Most of space saving came because I decided to add the power bank board and battery to the back of the screen, I had a PCB between the GPIO and the screen last time but this time I added the new power bank board I was using and managed to squeeze a battery in there too. I also added a button when pressed told you the battery level without powering on the pi and a switch to turn it on and off. There is also a micro USB port for charging the battery. I just managed to squeeze in a 2500mAh battery I took from the original PocketPi


The next height saving came when I redesigned the OTG USB hub. The keyboard I used on the original PocketPi used bluetooth 2.0, the raspberry pi didn’t like it so I had to turn off the on board bluetooth and use a bluetooth dongle. This required me to have a 2 port USB hub which took up lot of height in the build. This time around I sourced a bluetooth 3.0 keyboard with track pad so I didn’t need the dongle. I also soldered the USB hub straight to the OTG pads on the bottom of the raspberry pi, They can be easily removed if I ever have to move to a different pi in the future. The new hub gives me one full size USB port for plugging in flash drives or programming arduino’s.

Screen and GPIO

As before I used the waveshare 3.5″ 480×320 clone screen which is great for a portable desktop pi and terminal. The GPIO are broken out under the screen so you can use for addon’s or to develop hardware.

  2. I am kind of curious, what it the run time of the batteries with both the Pi and screen going?

    • I’m not too sure sorry, With the battery in my last PocketPi I would get hours of use out of it in between charges. It all depends what you are doing on it also
