LactateStat v1: common questions

What microcontroller does the LactateStat v1 use?

The LactateStat v1 is built around the NRF52832-QFAB-R, from the Nordic nRF family.

How big is the LactateStat v1 PCB?

The LactateStat v1 measures 34.1 × 26.5 mm and is 1.6 mm thick.

How many components are on the LactateStat v1?

41 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the LactateStat v1 design files?

From the emilekelund/LactateStat-Hardware-Resources repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the LactateStat v1 design in my own project?

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

Can I test firmware for the LactateStat v1 without the hardware?

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