Minimi: common questions

What microcontroller does the Minimi use?

The Minimi is built around the Seeed Studio XIAO ESP32C6, from the ESP32 family.

How big is the Minimi PCB?

The Minimi measures 22.4 × 31.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Minimi?

29 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Minimi design files?

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

Can I use the Minimi design in my own project?

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

Can I test firmware for the Minimi 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.
