Start by picking a board. You can build a basic K3NG unit on a standard Arduino (like an Uno, Mega, or Nano) connected to a breadboard. Or, for a cleaner and more professional result, you can use a purpose-built PCB like the (from DJ0MY/N7XG) or the K5BCQ board, which take all the guesswork out of wiring. The choice of board will dictate which components you need. The is a titan in the amateur radio (ham radio) community

is widely considered the "Swiss Army Knife" of Morse code keyers, offering a staggering range of features from Winkeyer emulation to PS2 keyboard support. While the project is legendary, its versatility can make the initial hardware setup feel daunting. If you’re looking to "repack" this classic schematic into a cleaner, more efficient build, here is how to approach it. 1. Choosing Your Brain: Nano vs. Mega
