The K3NG keyer offers several benefits to amateur radio operators: k3ng keyer schematic

The heart of the schematic is the ATMega328P (on Nano/Uno) or ATMega2560 (on Mega). The key pins to identify are: potentiometers for speed control

Optional LCD/I2C displays, potentiometers for speed control, and pushbuttons for memories. Basic K3NG Keyer Schematic Diagram k3ng keyer schematic
