Silas plugged the drive into Elias’s dusty laptop. A file folder opened, revealing a massive collection of files. The beauty of the K3NG schematic is its modularity
If you want, I can for a specific configuration (e.g., Nano + optoisolator keying + I2C LCD + speed pot). Just tell me which features you need. If you want, I can for a specific configuration (e
The K3NG firmware generates a sidetone square wave on a digital pin (usually D6 or D9 via PWM). However, a raw square wave is harsh and weak. The schematic typically includes:
