Quad unibody placement0: common questions

What microcontroller does the Quad unibody placement0 use?

The Quad unibody placement0 is built around the ESP32-C3-MINI-1-H4X, from the ESP32 family.

How big is the Quad unibody placement0 PCB?

The Quad unibody placement0 measures 50.8 × 45.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quad unibody placement0?

64 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Quad unibody placement0 design files?

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

Can I use the Quad unibody placement0 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 placement0 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.
