great video! what software are you using to test the servos?

WombatPanel. It works with my Serial Wombat firmware for the PIC24FJ256GA702. It's written in C#. There's a library of classes for all the things the Serial Wombat chip can do, and then the WombatPanel GUI is written on top of that. The GUI is based on Windows Forms, so it's Windows only. But the underlying libraries will run on anything that can run .Net core (such as raspberry pi). The interfaces match up on the libraries for C#, Arduino (C++) and (Micro)?Python. github.com/BroadwellConsultingInc/SerialWombatCsharpLib

If any custom PCBs may help? If so, would love to sponsor free ones! (PCBWay zoey)
