K3ng Keyer Schematic Repack ^hot^ -

project into a single, streamlined hardware design. Because the original K3NG code is designed to be extremely flexible—supporting everything from simple Arduino Unos Mega 2560s

Core Components of a Typical K3NG Repacked Schematic

Functional Clustering: The repack splits the single mess into logical modules. Page 1: Power & Microcontroller. Page 2: Keying Outputs & Transistor Buffers. Page 3: UI (Buttons, Encoder, LCD). Page 4: Audio Sidetone & Amplifier.
The "Minimum Viable" Layer: A good repack adds a bold border around the core components. It answers the question: "What do I need for just a basic iambic keyer?" Everything else is grayed out or on a separate sheet.
Pinout Liberation: The best repacks don't give you the pinout; they give you a color-coded legend and a blank table. They force you to open k3ng_keyer.ino, find the pin mappings, and write them in. This turns a schematic into a workbook.
Bill of Materials (BOM) Alignment: The original might say "10k resistor." The repack says "10k resistor (R12, used in voltage divider for speed pot)." It cross-references every component with the configuration macros in the code.

schematic! The goal was to take Anthony Good’s (K3NG) open-source masterpiece and refine the hardware layout for better usability and feature density. 🚀 What’s New in This Repack? Enhanced Memory Support: Optimized for the Arduino Mega 2560 , allowing you to enable memory-heavy features like CW Decoding Winkey Emulation LCD/OLED support without hitting the 32k limit of the Nano.
