Schematic __exclusive__ — K3ng Keyer

The represents one of the most flexible and feature-rich open-source CW (Morse Code) keyer designs available to the amateur radio community . Developed by Anthony Good (K3NG), this Arduino-based project rivals high-end commercial keyers by offering extensive customization through a modular code structure. Core Schematic Components

One of the key reasons to study the K3NG schematic is its support for a wide array of peripherals: k3ng/k3ng_cw_keyer: K3NG Arduino CW Keyer - GitHub k3ng keyer schematic

The brain of the operation is usually an Arduino Uno for basic setups or an Arduino Mega 2560 for builders who want to enable memory-intensive features like LCD displays and full WinKey emulation. The represents one of the most flexible and

An optional 10k or 100k pot allows for manual CW speed adjustment, typically ranging from 1 to 999 WPM. Advanced Hardware Options An optional 10k or 100k pot allows for

While the design is highly modular, a basic K3NG keyer schematic typically includes the following foundational elements:

Two digital pins (typically D2 and D5) are mapped to the left and right paddles to detect "dit" and "dah" inputs.
