Hi Andrea,

yes of course, but i wouldn't call it a PCB ;)

Just a strip pcb meant for prototyping.

The vertically arranged resistors are for limiting the LED current.

The horizontally arranged resistors are pullup resistors for the VFO A, B and PTT Buttons.

There are 3 KY-040 encoders completely with their own pcb and Button and Encoder Output pins.

I've tried to attach them to pins having interrupts in the arduino to have a better switching sense.

I really would like to extend it to have another bunch of controls on it.

I think a RX=TX (On Off), RX -> TX (Sync) would be cool. I also would like to add a Mode selector.

And the top of my list would be a little display to show the selected value, when selecting something ;)

But it had to be quickly available and it's working flawlessly since nearly a year.

Best regards

Chris

Hallo Chris,

May I ask you to show us, when you have spare time, a schematic of your arduino micro knob or at least a photo of the back of PCBs? 

Thank you very much :-)
