Full function Arduino CW keyer (K3NG)

I have created a little board using the Arduino Nano that can be built to what ever needs the user wants to implement. It is an erector set approach. It can be built with as many as 8 buttons, rotary encoder, etc. There are pins for most features that K3NG has implemented. The average cost to build a basic board is around $12.00 less case and extras such as the LCD display.

As of January 4, 2032 I am out of stock and working on an updated design.

For additional information please read our nKeyer Guide.

Features

Designed to implement only the features you desire
Powered by 5v - 15v dc (on board regulator)
Button headers from 1 to 8 buttons
Speed can be controlled by either an encoder or potentiometer
Headers for LCD display
Drives 8 ohm speaker
Uses open source code developed by K3NG
Headers for transmit LED

Description

This is an open source Arduino based CW (Morse Code) keyer developed by K3NG with a lot of features and flexibility, rivaling commercial keyers which often cost significantly more. 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 keyer is suitable as a standalone keyer or for use permanently installed inside a rig, especially homebrew QRP rigs. 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. More information can be found at Radio Artsian

3D Printed Enclosure

Joe Reed, N9JR has designed a nice 3D printed case and is making it available with it's own assembly guide:
