The K3NG schematic is famously flexible, allowing builders to "enable" or "disable" hardware features in the code to match their specific build: A Simple DIY “Unikeyer” Based on the K3NG Design k3ng keyer schematic

: Most builds use an Arduino Uno for basic needs or an Arduino Mega 2560 for memory-intensive features like LCDs and full macro support. if (dash_time <
