About the Open-ESPilot PCB

Open-ESPilot is an open source ESP32 PCB design by Tomas-Kuchta-FPV, published on GitHub under the CERN-OHL-W-2.0 license. It is a 2-layer board measuring 50.6 × 71.1 mm, with 98 components from 45 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N8, from the ESP32 family. Other key parts include the AMS1117-3.3, INA219AXD and C114218. By type, the board carries 21 capacitors, 17 resistors, 13 connectors, 6 diodes, 4 ICs and 4 jumpers.

It belongs with the robotics & motion and dev boards & breakouts designs in this gallery.

From the project

An open-source project to develop a custom ESP32-based flight controller designed primarily for use with ArduPilot. Focused on affordability, flexibility, and ease of integration with various robotic and UAV platforms.

This is a community-driven hardware project focused on creating an open and accessible Flight Controller (FC). The main focus is on being low-cost, availability, hackability and openness! That's why I've started this project to make an open-source and low-cost FC with the community.

The target firmware is ArduPilot, which is a powerful open-source autopilot system.

Open-ESPilot: common questions

What microcontroller does the Open-ESPilot use?

The Open-ESPilot is built around the ESP32-S3-WROOM-1-N8, from the ESP32 family.

How big is the Open-ESPilot PCB?

The Open-ESPilot measures 50.6 × 71.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Open-ESPilot?

98 components, from 45 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 Open-ESPilot design files?

From the Tomas-Kuchta-FPV/Open-ESPilot 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 Open-ESPilot design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which Tomas-Kuchta-FPV chose for the repository.

Can I test firmware for the Open-ESPilot 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.
