MiniSpeedCam-1.2: common questions

What microcontroller does the MiniSpeedCam-1.2 use?

The MiniSpeedCam-1.2 is built around the ESP32-S3-WROOM-1U-N8R8, from the ESP32 family.

How big is the MiniSpeedCam-1.2 PCB?

The MiniSpeedCam-1.2 measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MiniSpeedCam-1.2?

100 components, from 40 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 MiniSpeedCam-1.2 design files?

From the Valar-Systems/MiniSpeedCam 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 MiniSpeedCam-1.2 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which Valar-Systems chose for the repository.

Can I test firmware for the MiniSpeedCam-1.2 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.
