: A paddle (Left/Right) connected to digital pins and a 10k potentiometer for speed adjustment.
But if you’ve ever tried to build one from scratch, you hit a wall. Not the code—the schematic . k3ng keyer schematic repack
A successful repack often means redrawing the schematic in tools like KiCad, EAGLE, or even as a high-resolution PDF, with color-coded wires and clear pin mapping for the specific Arduino board. : A paddle (Left/Right) connected to digital pins
For amateur radio operators who enjoy Morse code (CW), the is nothing short of a legend. Developed by Anthony Good (K3NG), this open-source project transforms a simple Arduino (like the Uno, Nano, or Mega) into a feature-packed CW keyer that rivals commercial units costing hundreds of dollars. We’re talking about: A successful repack often means redrawing the schematic
If you’ve spent any time in the homebrew CW world, you know the is the gold standard. Written by Anthony Good (K3NG), this feature-packed keyer supports anything from a basic iambic paddle to a fully-featured contest keyer with a display, rotator control, and PSK31 beaconing.
