To make building easier, we have broken down the K3NG hardware architecture into five modular schematic blocks. You can mix and match these modules depending on your station's needs. Block A: The Minimalist Core & Paddle Input
: 16x2/20x4 LCDs, PS/2 keyboard, extensive CLI macros, multiple rig keying lines, optoisolation.
While the K3NG code runs on most AVR-based Arduinos, the is the gold standard for "repacked" builds due to its small footprint and built-in USB interface. Pin Mapping (Standard): D2 & D5: Paddle Left/Right (Dit/Dah) D13: PTT (Push-to-Talk) Output D11/D12: Keying Output (Transceiver connection) A0: Speed Potentiometer 2.

Open keyer_pin_settings.h and explicitly verify that the physical pins you soldered match the code definitions.
This is the recommended "getting started" configuration, allowing you to build a functional keyer on a breadboard Video 1.2.1 . Key Components List While the K3NG code runs on most AVR-based
