Msa: common questions

What microcontroller does the Msa use?

The Msa is built around the RP2040, from the RP2040/RP2350 family.

How big is the Msa PCB?

The Msa measures 47.8 × 9.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Msa?

53 components, from 31 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 Msa design files?

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

Can I use the Msa design in my own project?

Yes, under the terms of its MIT license, which aezrapour chose for the repository.

Can I test firmware for the Msa without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
