Open source nanovoltmeter
Please note this nanovoltmeter design was superseded by a new and better design, which will go public in this Github repository. Soon(TM)
Okay, I think I can do this. On the other hand, any reasonable mains-powered voltmeter has to have an isolated PSU section which powers the input dividers/amplifiers and ADC, so that the measurement potential could be unrelated to the digital section with all the user and communication IO - which is needed to be earthed or somewhere close to that potential. This one calls for either DC or AC power, but it could be combined by having a PSU operating from an…

Rnvm homer: common questions
What microcontroller does the Rnvm homer use?
The Rnvm homer is built around the XO21200HC4TG100C, from the FPGA family.
How big is the Rnvm homer PCB?
The Rnvm homer measures 175 × 103 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Rnvm homer?
219 components, from 65 distinct parts. The full bill of materials is listed on this page.
Where can I download the Rnvm homer design files?
From the jaromir-sukuba/nvm repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Rnvm homer design in my own project?
The repository has no license, so all rights stay with jaromir-sukuba. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Rnvm homer without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
