Home copter 2: common questions

What microcontroller does the Home copter 2 use?

The Home copter 2 is built around the ESP32-C3-MINI-1-H4X, from the ESP32 family.

How big is the Home copter 2 PCB?

The Home copter 2 measures 41.9 × 38.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Home copter 2?

63 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Home copter 2 design files?

From the ajwock/quadcopter repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Home copter 2 design in my own project?

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

Can I test firmware for the Home copter 2 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.
