I’ve redrawn the K3NG v2023 core into four logical sheets. Here’s the breakdown.
Jump to the “Inputs” block. The repack shows a 0.1uF capacitor across each paddle switch to debounce (optional but recommended). Paddle left → D3, right → D2. GND is common. k3ng keyer schematic repack
The heart of the repack is the microcontroller pinout table. A good repack will include: I’ve redrawn the K3NG v2023 core into four logical sheets
Example entry from a repack:
| Function | Uno/Nano Pin | Mega Pin | Firmware #define |
|----------------|--------------|----------|-----------------------------|
| CW Output | D13 (or D8) | D13 | #define cw_output_pin 13 |
| Paddle Left | D3 | D3 | #define paddle_left_pin 3 |
| Paddle Right | D2 | D2 | #define paddle_right_pin 2|
| Speed Pot | A0 | A0 | #define speed_pot_pin 0 | Example entry from a repack: | Function |
A repack typically presents this as a large table or multi-page diagram with clear cross-references.
