MateRix: common questions

What microcontroller does the MateRix use?

The MateRix is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the MateRix PCB?

The MateRix measures 40 × 69 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MateRix?

145 components, from 27 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 MateRix design files?

From the FBIopeningUPP/MateRix 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 MateRix design in my own project?

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

Can I test firmware for the MateRix 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.
