Mx: common questions

What microcontroller does the Mx use?

The Mx is built around the XIAO_nRF52840, from the Nordic nRF family.

How big is the Mx PCB?

The Mx measures 134.9 × 111.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mx?

63 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mx design files?

From the Diwamoto/sage60 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mx design in my own project?

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

Can I test firmware for the Mx 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.
