Esp32-c3: common questions

What microcontroller does the Esp32-c3 use?

The Esp32-c3 is built around the ESP32-C3, from the ESP32 family.

How big is the Esp32-c3 PCB?

The Esp32-c3 measures 45.7 × 21.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-c3?

32 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-c3 design files?

From the TadeasFrycak/esp32-c3 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32-c3 design in my own project?

Yes, under the terms of its GPL-3.0 license, which TadeasFrycak chose for the repository.

Can I test firmware for the Esp32-c3 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.
