Mni drone: common questions

What microcontroller does the Mni drone use?

The Mni drone is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Mni drone PCB?

The Mni drone measures 102.4 × 102.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mni drone?

72 components, from 34 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 Mni drone design files?

From the harris8099/Kicad-projects 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 Mni drone design in my own project?

The repository has no license, so all rights stay with harris8099. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Mni drone 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.
