A fully repacked K3NG schematic should be modular. This allows you to easily include or exclude features during the PCB layout phase.

Before warming up your soldering iron, you must pick your silicon. Because the code is highly modular, you can comment out unused features to fit small chips, or unleash the full software suite on larger microcontrollers.

This guide breaks down how to repack the K3NG keyer schematic for modern, efficient circuit board production. 1. Core Architecture Changes

| Mistake | Why It Happens | How the Repack Helps | | :--- | :--- | :--- | | | Dit and Dah pins swapped in code or wiring. | Repack shows physical orientation. | | Floating Inputs | No pull-up resistors on paddle lines. | Repack explicitly shows 10kΩ from pin to +5V. | | Key Output Always Active | MOSFET gate tied to 5V without current-limiting resistor. | Repack highlights the 220Ω series resistor. | | LCD Glitches | Missing I2C pull-ups on SDA/SCL. | Repack includes 4.7kΩ resistors on I2C lines. |

However, there is one persistent frustration that unites newcomers and experienced builders alike: Before warming up your soldering iron, you must

Note: Avoid the old Arduino Nano V2.x (ATmega168), as its 16 KB memory is fundamentally insufficient for modern K3NG code branches. Core Circuit Architecture (The Repack Blueprint)
