Meenie: common questions

What microcontroller does the Meenie use?

The Meenie is built around the NRF52840-QIAA-R, from the Nordic nRF family.

How big is the Meenie PCB?

The Meenie measures 13.6 × 9.4 mm, has 8 copper layers and is 0.991 mm thick.

How many components are on the Meenie?

32 components, from 24 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 Meenie design files?

From the RobbyV2/meenie_controller 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 Meenie design in my own project?

The repository has no license, so all rights stay with RobbyV2. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Meenie 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.
