This project has base on the K3NG Arduino keyer open-source firmware adding many features and flexibility.
The firmware is open source code provided by K3NG so you can customize it to fit your needs.
The Keyer is suitable as a standalone keyer or for keying the radio via the USB port from a connected computer and your favoured contest logging software or for daily operation.
