Esp32c3 controller: common questions

What microcontroller does the Esp32c3 controller use?

The Esp32c3 controller is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the Esp32c3 controller PCB?

The Esp32c3 controller measures 85 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32c3 controller?

37 components, from 19 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 controller design files?

From the 1999AZZAR/pcb-skill 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 controller design in my own project?

Yes, under the terms of its MIT license, which 1999AZZAR chose for the repository.

Can I test firmware for the Esp32c3 controller 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.
