About the Drone PCB

Drone is an open source ESP32 PCB design by Tomnwol, published on GitHub. It is a 2-layer board measuring 53.1 × 93.3 mm, with 11 components from 9 distinct parts.

Its main chip is the ESP32-DEVKIT-V1, from the ESP32 family. Other key parts include the SN74AHCT125N. By type, the board carries 4 resistors, 2 ICs, 2 diodes and 1 connector.

It belongs with the robotics & motion, sensors and iot & wireless designs in this gallery.

From the project

Git du projet drone de Robotech 2025 / 2026

ESP32-based 5" drone built by the Robotech team. Attitude is estimated from a 9-axis IMU, then converted into motor commands through a PID loop. Control and telemetry go over the ESP32's built-in Wi-Fi (UDP).

A 9-axis IMU (accelerometer, gyroscope, magnetometer) feeds a Madgwick AHRS filter to estimate attitude. Angular commands from that estimate drive the motors via DShot.

Drone: common questions

What microcontroller does the Drone use?

The Drone is built around the ESP32-DEVKIT-V1, from the ESP32 family.

How big is the Drone PCB?

The Drone measures 53.1 × 93.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Drone?

11 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Drone design files?

From the Tomnwol/drone-robotech repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Drone design in my own project?

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

Can I test firmware for the Drone 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.
