C.L.A.S: common questions

What microcontroller does the C.L.A.S use?

The C.L.A.S is built around the ESP32-S3-DEVKITC-1-N8R2, from the ESP32 family.

How big is the C.L.A.S PCB?

The C.L.A.S measures 334.5 × 135.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the C.L.A.S?

13 components, from 4 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 C.L.A.S design files?

From the YoussefAymanJo/C.L.A.S 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 C.L.A.S design in my own project?

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

Can I test firmware for the C.L.A.S 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.
