The daddelkischde is a circuit board kit to build a Raspberry Pi Zero into a classic Game Boy case to play old (handheld) console games on it. The most important electronic components are already included on the boards. In combination with other parts and free software you can build a portable retro console.


  • SNES button layout (D-pad, Start, Select, A, B, X, Y and shoulder buttons L and R)
  • Integrated charging circuit for LiPo batteries (charging and playing is possible at the same time)
  • Stereo headphone jack with volume control knob
  • Audio amplifier for a mono speaker
  • 2-port USB hub
  • USB A port for external devices such as keyboard, additional game pad, USB stick etc.
  • Micro USB port for charging
  • Analog-to-digital converter for measuring the battery voltage (matching Python script for displaying a battery icon is available for download)
  • Soldering pads for LEDs (Device powered on, empty battery, charging, fully charged)
  • STL files of the holding components for 3D printers free to download


  • Main PCB
  • Shoulder buttons PCB
  • Headphone jack
  • Stereo volume control knob
  • 2x20 pin pin header

To build a complete Game Boy Zero you will need additional parts. You can find a parts list under build.


Where does the name daddelkischde come from? Simple: That's how we call our selfmade Game Boys here in the Kurpfalz (region in southern Germany): Daddel-Kiste! "Daddeln" means to play computer games, "Kiste" is a box.
