About the C64 SkeletonKey PCB

C64 SkeletonKey is an open source PCB design by tebl, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 10.4 × 55.3 mm, with 5 components from 5 distinct parts.

By type, the board carries 4 jumpers and 1 connector.

It belongs with the retro computing, keyboards and test & measurement designs in this gallery.

From the project

WASD-style joystick for vintage computers. With an added Arduino Pro Micro you can use it as a USB-keyboard, so if you wanted a DIY streamdeck or Macro-keyboard - then the C64 JoyKEY can do that as well.

With options to handle multiple types of systems comes complexity, you'll have to make a few decisions on what you want out of the C64 JoyKEY. Do I only want to use it as a joystick replacement on vintage systems, ideally with 2-3 fire buttons where supported? If so, then you won't need the Arduino Pro Micro.

Want to use it on a modern system as a WASD-style keyboard or a gamepad, then install it - a common use of these types of devices is as a macro-keyboard or a stream-deck. Note that compared to many similar solutions, the microcontroller is not required for use with any of the vintage…
