Mannuino: common questions

What microcontroller does the Mannuino use?

The Mannuino is built around the ESP32-S3-WROOM-2, from the ESP32 family.

How big is the Mannuino PCB?

The Mannuino measures 34 × 41.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mannuino?

22 components, from 14 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 Mannuino design files?

From the mannireis/mannuino 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 Mannuino design in my own project?

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

Can I test firmware for the Mannuino 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.
