Keyboard shield for Apple IIc or IIc+


Connect the keyboard of a classic Apple IIc or IIC+ to a modern system, whether you're building a stealthy system for retro gaming emulation, an '80s themed iPad dock, or just really prefer the super clicky feel of those old keys. Perfect for embedding a Raspberry Pi in a retro shell!


These boards are shields that plug into the PJRC Teensy Arduino clone. The Teensy provides the USB HID (human interface device) code and is easily programmable to match different keyboard layouts, remap broken or custom keys, or add additional functionality.


Flashing firmware requires:

  • RetroConnector firmware
  • Arduino software
  • teensyduino library
  • keypad.h library

Full versions come completely soldered, firmware flashed for US English keyboard layout

  1. I received a 1.4 apple iie keyboard shield. On the pc everything is fine. On the raspberry pi it has the caps and lower case reversed. Nothing else is. I have thoroughly checked the shift keys with a multimeter plus it fully functions correctly on the other keys. Retropie on the pi defaults to a uk keyboard. Is there a us keyboard i need to switch the settings to?
