Use a metal "mint tin" or aluminum project box to prevent RF interference from tripping the Arduino.
The K3NG Wiki contains the authoritative pinout and feature definitions. Arduino CW Keyer | Morse Code | K3NG Project
| Issue with Original | Advantage of Repack | |---------------------|----------------------| | Wires crossing over unrelated blocks | Modular layout | | Repeated net labels scattered | One clear power bus and ground | | Hard to find input pull-ups | Dedicated “Input Section” | | Unclear component values | Consolidated BOM (Bill of Materials) near each block | k3ng keyer schematic repack
The genius of the K3NG keyer lies in its feature-rich, open-source code, which is the brain of every version you will encounter. Created by Anthony Good (K3NG), the firmware rivals commercial keyers that cost significantly more. Its long list of features includes:
Have you built a K3NG keyer? What was the hardest part of the wiring for you? Drop a comment below or find me on QRZ. Use a metal "mint tin" or aluminum project
Thus, the holy grail of the K3NG repack isn't a static image. It is the —a Fritzing, KiCad, or even a DIYLC (DIY Layout Creator) project where you check boxes:
Here is a structured post you can use to share your "repack" project with the amateur radio community. 📡 Project Showcase: K3NG CW Keyer Schematic Repack I've been working on a "repacked" version of the legendary K3NG Arduino CW Keyer Created by Anthony Good (K3NG), the firmware rivals
A great repack will include a decision flowchart or table to help the builder choose based on available pins and library support.
Specifically K3NG's official repo for the code and YU7AOP's repo for specialized Mega/Nano PCB layouts.
A "repacked" schematic often focuses on reducing the footprint while maintaining reliability. Key areas to simplify include: A tiny and open source CW keyer - Dhakajack - Templaro
A small piezo speaker or speaker driven by a transistor from an Arduino digital pin (often D11). Key Build Options
