Xiao esp32c3: common questions

What microcontroller does the Xiao esp32c3 use?

The Xiao esp32c3 is built around the Module_XIAO-ESP32C3_SocketSMD, from the ESP32 family.

How big is the Xiao esp32c3 PCB?

The Xiao esp32c3 measures 106.9 × 96.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Xiao esp32c3?

24 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Xiao esp32c3 design files?

From the MiroKeimioniemi/digital-fabrication-portfolio repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Xiao esp32c3 design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Xiao esp32c3 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.
