R3M1XXX: common questions

What microcontroller does the R3M1XXX use?

The R3M1XXX is built around the Raspberry_Pi_Pico_THT, from the Raspberry Pi family.

How big is the R3M1XXX PCB?

The R3M1XXX measures 50 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the R3M1XXX?

180 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the R3M1XXX design files?

From the jvegaf/R3M1XXX repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the R3M1XXX design in my own project?

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

Can I test firmware for the R3M1XXX without the hardware?

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