DIY CW Decoder Board LCD

This DIY kit comprises a single 101 mm × 50 mm printed circuit board designed for full component-level assembly. It runs on 9 V DC power with a measured consumption of 33 mA. The board processes incoming CW audio to detect dots, dashes, and timing gaps, converting them into readable text shown on its integrated LCD display. Transmission speed is calculated and displayed in real time. A physical push button supports offline, tactile Morse encoding practice. All parts are included for hand-soldering — making it suitable for electronics courses, radio licensing preparation, and hobbyist skill development in analog-digital interfacing and real-time signal processing.
