Quad unibody: common questions

What microcontroller does the Quad unibody use?

The Quad unibody is built around the ESP32-C3-MINI-1-H4X, from the ESP32 family.

How big is the Quad unibody PCB?

The Quad unibody measures 63.5 × 55.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quad unibody?

67 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Quad unibody 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 Quad unibody 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 Quad unibody 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.
