OpenAV
About the OpenAV PCB
OpenAV is an open source ESP32 PCB design by JIBSIL, published on GitHub under the MIT license. It is a 2-layer board measuring 70.3 × 53.9 mm, with 35 components from 25 distinct parts.
Its main chip is the ESP32-S3-MINI-1U, from the ESP32 family. Other key parts include the SIM800C, Ra-01, MPU-6050, FXMA108 and CH340N. By type, the board carries 15 capacitors, 8 ICs, 6 resistors, 3 connectors, 2 antennas and 1 LED.

OpenAV: common questions
What microcontroller does the OpenAV use?
The OpenAV is built around the ESP32-S3-MINI-1U, from the ESP32 family.
How big is the OpenAV PCB?
The OpenAV measures 70.3 × 53.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the OpenAV?
35 components, from 25 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 OpenAV design files?
From the JIBSIL/OpenAV 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 OpenAV design in my own project?
Yes, under the terms of its MIT license, which JIBSIL chose for the repository.
Can I test firmware for the OpenAV 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.
