From the project
A small, open hardware DMM
This is the PCB design and code for a 4.5 digit DMM/ instrumentation module. It is designed and written primairly for Arduino-style development boards.
I've developed this DMM in my work testing and troubleshooting electronics to make my life easier.
I've had Deep-Wiki index my documentation. It did a mostly okay job. You can read its summary here: [](https://deepwiki.com/oihdesigns/Micro-DMM)
