FMN potentiostat: common questions

What microcontroller does the FMN potentiostat use?

The FMN potentiostat is built around the ESP32-H2-MINI-1-H2, from the ESP32 family.

How big is the FMN potentiostat PCB?

The FMN potentiostat measures 30 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the FMN potentiostat?

50 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the FMN potentiostat design files?

From the Kiya86/Terasaki-Main- repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the FMN potentiostat design in my own project?

The repository has no license, so all rights stay with Kiya86. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the FMN potentiostat without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
