About the Quadcopter PCB

Quadcopter is an open source ESP32 PCB design by markusheimerl, published on GitHub under the Unlicense license. It is a 2-layer board measuring 75.1 × 75.1 mm, with 60 components from 33 distinct parts.

Its main chip is the C2913202, from the ESP32 family. Other key parts include the C5368700, C28060 and C32574. By type, the board carries 21 resistors, 13 capacitors, 5 connectors, 4 ICs, 4 transistors and 4 diodes.

It belongs with the robotics & motion and power & battery designs in this gallery.

From the project

A quadcopter simulation & hardware design

Flight controller and frame on a single 2‑layer PCB, written in tscircuit. index.tsx is the whole design: parts, schematic, placement and every copper track (drawn by hand, no autorouter). The four arms are the frame; the electronics sit in the 44.8 mm core. Each motor connector sits in its corner with the cable opening facing down the arm.

Quadcopter: common questions

What microcontroller does the Quadcopter use?

The Quadcopter is built around the C2913202, from the ESP32 family.

How big is the Quadcopter PCB?

The Quadcopter measures 75.1 × 75.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quadcopter?

60 components, from 33 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 Quadcopter design files?

From the markusheimerl/quadcopter 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 Quadcopter design in my own project?

Yes, under the terms of its Unlicense license, which markusheimerl chose for the repository.

Can I test firmware for the Quadcopter 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.
