Lightbeam-S3: common questions

What microcontroller does the Lightbeam-S3 use?

The Lightbeam-S3 is built around the ESP32-S3-WROOM-2-N32R8V, from the ESP32 family.

How big is the Lightbeam-S3 PCB?

The Lightbeam-S3 measures 250 × 25 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Lightbeam-S3?

68 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lightbeam-S3 design files?

From the besser435/Lightbeam-S3 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lightbeam-S3 design in my own project?

The repository has no license, so all rights stay with besser435. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Lightbeam-S3 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.
