Esp32c3-smart board: common questions

What microcontroller does the Esp32c3-smart board use?

The Esp32c3-smart board is built around the ESP32-C3, from the ESP32 family.

How big is the Esp32c3-smart board?

The Esp32c3-smart board measures 42.6 × 45.7 mm, has 4 copper layers and is 1.547 mm thick.

How many components are on the Esp32c3-smart board?

64 components, from 32 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 Esp32c3-smart board design files?

From the petrovgp/esp32c3-smart-board 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 Esp32c3-smart board design in my own project?

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

Can I test firmware for the Esp32c3-smart 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.
