About the ESP32-Gimbal PCB

ESP32-Gimbal is an open source ESP32 PCB design by Visaging, published on GitHub under the MIT license. It is a 2-layer board measuring 32.3 × 87.6 mm, with 59 components from 33 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the CN3303, TPS563200 and DRV8313PWP. By type, the board carries 22 capacitors, 14 connectors, 13 resistors, 6 ICs, 2 inductors and 1 transistor.

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

From the project

A high-performance, open-source 3-axis smartphone gimbal built from scratch using a custom PCB and the SimpleFOC library. It features real-time stabilization, native USB-C programming, and custom motion modes.

- [ ] Bluetooth App: Control the gimbal with a phone (because looking at two screens is better than one). - [ ] Face Tracking: If I can figure out how to run AI on this chip without it catching fire.

Feel free to steal this code, modify it, or sell it. However, if your phone falls out and breaks because you set the PID values wrong, I legally never met you.

ESP32-Gimbal: common questions

What microcontroller does the ESP32-Gimbal use?

The ESP32-Gimbal is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the ESP32-Gimbal PCB?

The ESP32-Gimbal measures 32.3 × 87.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-Gimbal?

59 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 ESP32-Gimbal design files?

From the Visaging/ESP32-Gimbal 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 ESP32-Gimbal design in my own project?

Yes, under the terms of its MIT license, which Visaging chose for the repository.

Can I test firmware for the ESP32-Gimbal 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.
