Drone updated: common questions

What microcontroller does the Drone updated use?

The Drone updated is built around the AO3401A, from the ESP32 family.

How big is the Drone updated PCB?

The Drone updated measures 47.6 × 46 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Drone updated?

75 components, from 32 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 Drone updated design files?

From the nikhilChandra-coder/drone_updated 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 Drone updated design in my own project?

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

Can I test firmware for the Drone updated 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.
