S3 cam: common questions
What microcontroller does the S3 cam use?
The S3 cam is built around the ESP32-S3-WROOM-1-N8R2, from the ESP32 family.
How big is the S3 cam PCB?
The S3 cam measures 44.5 × 33 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the S3 cam?
58 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the S3 cam design files?
From the ajwock/quadcopter repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the S3 cam design in my own project?
The repository has no license, so all rights stay with ajwock. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the S3 cam 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.
