From the project

K9HZ Electronic Kits

The intent of this PCB is to simplify the build process, make it easier to produce a polished final product, and replace some components with less expensive alternatives.

- The slice tuning encoders are attached directly to the front panel, with openings in the main PCB to allow the encoders to pass through. - The front side of the PCB holds the display, encoders and push buttons. - The reverse side of the PCB holds the Teensy 4.1 micro controller, I/O Expanders, header connectors, resistors and capacitors.
