The KiCad project lives in the LESA-RPI/hfs.main repository on GitHub; these links point at the commit this page was built from.

ESP32Sensor-LED board: common questions

What microcontroller does the ESP32Sensor-LED board use?

The ESP32Sensor-LED board is built around the ESP32-C3-WROOM-02-N4, from the ESP32 family.

How big is the ESP32Sensor-LED board?

The ESP32Sensor-LED board measures 58 × 58 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32Sensor-LED board?

48 components, from 31 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 ESP32Sensor-LED board design files?

From the LESA-RPI/hfs.main 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 ESP32Sensor-LED board design in my own project?

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

Can I test firmware for the ESP32Sensor-LED 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.
