This is Part 2 of the upgrade project to allow the 5 volt Precision Reference standard covered in my previous video to be switched to give 100mV, 1V, 5V and 10V outputs. In this final part I will cover the final build on a custom PCB, calibrate and box the unit.
The link to Part 1 is below:
Also, here’s a link to my PCB tutorial video:
Below are 4 links to the PDF files which contains the PCB artwork, component layout, circuit diagram, parts list and front fascia artwork:
