A circuit board and parts kits called the nanoKeyer is available from DJ0MY, Hamshop offers a kit called Open CW Keyer , RemoteQTH offers the Open Interface. It’s open source code so you can fully customize it to fit your needs and also perhaps learn from it or find coding ideas for other projects.

This keyer is suitable as a standalone keyer or for use permanently installed inside a rig, especially homebrew QRP rigs. The code can be used with a full blown Arduino board or an AVR microcontroller chip can be programmed and used directly in a circuit. This is an open source Arduino based CW (Morse Code) keyer with a lot of features and flexibility, rivaling commercial keyers which often cost significantly more.
