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.

Enclosure and ergonomics

To give you a concrete idea of how these schematics come together, here are a few popular build variations.

To hear what you're sending, a sidetone oscillator is essential. The K3NG keyer uses one of the Arduino's output pins to generate an audio frequency. This pin drives a small speaker or piezo element.

Before diving into where to find a repack, let’s break down what any good repacked schematic include. If you are designing your own repack, these are the essential blocks: k3ng keyer schematic repack

Build the circuit on a solderless breadboard first, following the pin connections in section 2.

Ultimate Guide to the K3NG Keyer Schematic Repack The K3NG Arduino CW Keyer is the gold standard for amateur radio operators seeking a customizable, feature-rich Morse code keyer. Created by Anthony Good (K3NG), this open-source project transforms a basic Arduino into a powerful powerhouse supporting features like Command Mode, memory macros, USB keyboard interfaces, and dual-paddle operation.

The K3NG keyer is highly modular. You can build a bare-minimum version using just an Arduino Nano and a few resistors, or scale up to a full-featured station controller with LCD displays, rotary encoders, and physical status LEDs. So, you have a schematic, and you're ready to build

Support for I2C LCD (16x2 or 20x4) to show speed and sent text. Critical Documentation

A clean schematic repack divides the K3NG keyer into five functional blocks. Here is how to wire each section. 1. The Microcontroller (Arduino Nano)
