Stampy - RP2040 USB-C Controller Board for Handwiring


Heavily inspired by the Postage Board Mini by LifeIsOnTheWire, Stampy is an RP2040-based version of it for doing a handwired build.

Coming Soon! Production status

What is Stampy?

Stampy is a controller board meant to assist with the construction of a handwired keyboard. Instead of using some other daughterboard like the Pro Micro, Elite-C, etc., Stampy gets soldered directly to 3 switches, meaning that no extra space below the controller is needed.

Goes great with the Amoeba Single-switch PCBs!
