K3ng Keyer Schematic ((install)) Instant

The Case of the Trembling Paddle

• Digital I/O Pins: Configured for paddle inputs (dot, dash), function buttons, and PTT.
• Analog Pins: Used for potentiometers (speed, volume, weighting).
• Interrupt Pins: Critical for handling paddle inputs without missing a dit or dah. Typically, pins 2 and 3 are assigned to dot and dash.

1. Overview of the K3NG Keyer

The K3NG Keyer is not a single fixed schematic but a modular design around an Arduino (Uno, Nano, Mega, Teensy, etc.).
It supports: k3ng keyer schematic

The K3NG keyer schematic consists of several key components: The Case of the Trembling Paddle
