MPE HUB: common questions

What microcontroller does the MPE HUB use?

The MPE HUB is built around the ESP32-S3-MINI-1-N4R2, from the ESP32 family.

How big is the MPE HUB PCB?

The MPE HUB measures 117 × 107 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the MPE HUB?

235 components, from 58 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 MPE HUB design files?

From the felixmanfredi/MPE_HUB 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 MPE HUB design in my own project?

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

Can I test firmware for the MPE HUB 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.
