Hardware projects: common questions

What microcontroller does the Hardware projects use?

The Hardware projects is built around the WIRELM-SMD_ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Hardware projects PCB?

The Hardware projects measures 61.9 × 64 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hardware projects?

57 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hardware projects design files?

From the AndreyCortez/hardware_projects repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Hardware projects design in my own project?

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

Can I test firmware for the Hardware projects 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.
