This is an open source Arduino based CW (Morse Code) keyer with a lot of features and flexibility, rivaling other commercial keyers which often cost significantly more. The Arduino code comes from K3NG, and it’s an 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. We redesigned the PCB, which could be fit into a compact aluminum enclosure, and trimmed the code so as to fit the features of AVR mega 2560. The Funtronics K3NG Keyer integrates nearly all of the features & functions of the K3NG’s arduino code, such as LCD display, USB keyboard, rotary encoder and CW decoder etc. Moreover, there are some spare IOs left on the pcb, which could be left for the feature new features & functions.
