Project Description
The Mini AI Camera Module is a compact platform based on the ESP32-S3, combining a standard visible-light camera with a LiDAR sensor. The module is designed as a low-cost solution for implementing simple AI algorithms, image recognition, and basic 3D depth perception.
This project includes:
- OV5640 visible-light camera (5 MP)
- VL53L5CX LiDAR camera with an 8×8 pixel depth map
(A future hardware revision is planned to include the VL53L9CX sensor featuring a 54×42 pixel resolution.)
Key Features
-
Compact size: 25×25 mm
The module includes mounting holes for easy installation, e.g., in mobile robots. -
Two complementary imaging systems
- OV5640 – 5 MP visible-light camera
- VL53L5CX – 8×8 pixel LiDAR sensor
-
Low production cost
- Uses popular and cost-effective electronic components
- PCB designed with simple manufacturing requirements
- Complete JLCPCB production files included
-
Ideal for autonomous and IoT projects
Suitable for robotics, autonomous vehicles, perception systems, and IoT devices. -
Wireless connectivity
With the ESP32-S3, the module supports:- WiFi
- Bluetooth
- ESP-NOW
-
Convenient USB and UART interfaces
- Vertical USB-C port allows direct mounting to a robot chassis
- SBU1 and SBU2 lines are exposed as UART, enabling easy integration with external devices
-
Easy to use and based on open-source libraries
The project is designed to be simple to integrate and develop with. It relies on well-maintained open-source libraries (including SparkFun drivers) as well as built-in components from the ESP-IDF framework. -
Open-source project (Apache 2.0 License)
The entire project is fully open-source and released under the Apache 2.0 license, allowing both personal and commercial use with minimal restrictions.

Questions
How big is the Mini AI Camera Module PCB?
It measures 25 × 25 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mini AI Camera Module use?
68 parts, built around the ESP32-S3FH4R2, AP63203WU, CH213K and ESD5Z5.0. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Mini AI Camera Module KiCad files?
From the bartsil/Mini-AI-Camera-Module repository on GitHub, at the commit this page was made from: the board is PCB/KiCad/PCB.kicad_pcb and its schematic PCB/KiCad/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini AI Camera Module design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
