Please note this nanovoltmeter design was superseded by a new and better design, which will go public in this Github repository.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 marge: common questions

What microcontroller does the Rnvm marge use?

The Rnvm marge is built around the STM32F373VBT6, from the STM32 family.

How big is the Rnvm marge PCB?

The Rnvm marge measures 151 × 131 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rnvm marge?

215 components, from 79 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rnvm marge 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 marge 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 marge without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
