K3ng Keyer Schematic Repack: [cracked]

A very specific request!

If you are designing a custom PCB, consider adding these "Pro" features: k3ng keyer schematic repack

Component choices & layout

The keyer uses the Arduino’s internal pull-up resistors, but for high-RF environments (common in ham shacks), adding external 0.01µF capacitors from the Dit and Dah lines to ground is highly recommended to prevent "ghost" keying. B. The Keying Circuit (Optoisolator vs. Transistor) A very specific request

In short, a repack is a bridge between the powerful but scattered original design and the real-world builder.
