Sensor Board: common questions

What microcontroller does the Sensor Board use?

The Sensor Board is built around the ESP32-S3-WROOM-2, from the ESP32 family.

How big is the Sensor Board?

The Sensor Board measures 86.6 × 82.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sensor Board?

29 components, from 12 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 Sensor Board design files?

From the HKUST-Red-Bird-Racing-EVRT/GEN5_ELEC 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 Sensor Board design in my own project?

The repository has no license, so all rights stay with HKUST-Red-Bird-Racing-EVRT. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 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.
