K3ng Keyer Schematic

For those seeking a more defined path, the project by N7XG offers a fantastic, ready-to-use schematic and PCB. This popular variant is built around an Arduino Nano 3.0 and includes a 5V Mini-360 buck regulator for power input, LEDs, headers, and built-in transistor drivers for keying. The full schematic is available in its manual. The parts list from the nKeyer gives specific values that are a great starting point for understanding the component requirements of a K3NG keyer.

"Rube Goldberg would be proud," Silas grunted. "But if you want elegance, you don't need a bucket of logic chips. You need the K3NG."

While the software handles most debouncing, some schematics include small 0.01µF capacitors across the paddle lines to filter out RF interference. 4. Audio Sidetone k3ng keyer schematic

An optional small speaker or piezo buzzer connected to a digital pin (often with a current-limiting resistor) to provide audio feedback of the Morse code being sent. Speed Control: 10k ohm potentiometer

Adding a display lets you see your current WPM, operating mode, and even decodes your sent characters on screen. For those seeking a more defined path, the

Typically powered via USB (5V) or a regulated 7-12V source applied to the Vin pin. 2. Paddle Input
