16 x Servo Module – 1st draft

Just the first 3D draft of my Servo Module. I still have the Raspberry PI Zero W hanging on the back of this – we don’t need to populate that header, but had plenty of room for it so just left it there. on top left you see jumpers to select Servo and Servo Signal voltage. On right you see a classic 3 x 16 header for servo connectors with the photo coupler providing a complete isolated Servo module.

I have a few changes I need to do – firstly I want to investigate how to add a current sensor with full isolation – possible using a photo coupler.
