This is the board that was used to hand-assemble early prototypes of the first two ArduSat satellites that went into space in 2013. We have a small number of these left over from that production run, so this is your chance to own a piece of Arduino and space history!

Build a custom CubeSat satellite module by combining your own parts and sensors with the LibreSat Prototyping Module. Excellent for non-satellite projects too.

This module is primarily designed for prototyping experimental hardware on the ground and for testing on HAB (high altitude balloon) and sounding-rocket flights. Perfect if you're planning to have an experiment performed on an ArduSat mission and you want to assemble hardware locally for testing.


  • Gold plated PCB.
  • Huge 651 hole prototyping area (all holes separate).
