Initial Release

In this release, basic drawings, schemes, and PCB board are given. I added a detailed explanation of the usage of the PCB, its purpose, and its limits. I know that there are missing parts, I will add them as you request. However, I expect that, with minimal knowledge of ADC, and Wheatstone Bridges, you will be able to use this extension quite easily. On any part that is not clear or that you have trouble with, do not hesitate to contact me. I will help you as much as I can.
