How to use it

Hardware connection

  • Attach Raspberry Pi Zero/Zero W to GamePi20 extension board. Note that you need to first set up SD card according to the instruction below, before you assemble it.
  • Mount the extension board to the metal box
  • Place conductive rubber mats and buttons on it, finally assemble the front panel.

To use the GamePi20, you can use the pre-configured image or install driver to a fresh image yourself.

Method 1: Pre-configured Images

  • Here we provide a pre-configured image, you can download and test
OS Version Raspberry Pi Default user/password Download link
Recalbox 6.0-DragonBlaze Raspberry Pi 1/Zero/Zero W root/recalboxroot Google Drive
Retropie v4.4 Raspberry Pi 1/Zero/Zero W pi/raspberry Google Drive
  • Download image file, unzip and write it to SD card
  • Insert the SD card to Raspberry Pi, assemble GamePi20 as #Hardware connection
  • turn the switch into ON. Generally, LCD is light on and Raspberry Pi is booting. It may cause about 2 minutes for Raspberry Pi 1/zero/zero W to starting.
    • Raspberry Pi is failed to start if the battery is low. In this case, you can connect 5V/2A power adapter to the Power interface for charging. Capacity indicators
