Minions: common questions

What microcontroller does the Minions use?

The Minions is built around the NRF52832-QFXX, from the Nordic nRF family.

How big is the Minions PCB?

The Minions measures 102.1 × 99.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Minions?

101 components, from 52 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 Minions design files?

From the ahsanu123/sudi-keyboard 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 Minions design in my own project?

Yes, under the terms of its MIT license, which ahsanu123 chose for the repository.

Can I test firmware for the Minions without the hardware?

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