S3 sensor board: common questions
What microcontroller does the S3 sensor board use?
The S3 sensor board is built around the ESP32-S3, from the ESP32 family.
How big is the S3 sensor board?
The S3 sensor board measures 20 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the S3 sensor board?
68 components, from 41 distinct parts. The full bill of materials is listed on this page.
Where can I download the S3 sensor board design files?
From the benvonhandorf/esp32_sensor_board 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 sensor board design in my own project?
Yes, under the terms of its MIT license, which benvonhandorf chose for the repository.
Can I test firmware for the S3 sensor board 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.
