Drone: common questions

What microcontroller does the Drone use?

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

How big is the Drone PCB?

The Drone measures 117.4 × 117.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Drone?

49 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Drone design files?

From the rmingon/drone-uwb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Drone design in my own project?

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

Can I test firmware for the 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.
