ESP32-C6: common questions

What microcontroller does the ESP32-C6 use?

The ESP32-C6 is built around the BQ25185DLHR, from the ESP32 family.

How big is the ESP32-C6 PCB?

The ESP32-C6 measures 17.8 × 30.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-C6?

43 components, from 30 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 ESP32-C6 design files?

From the uutzinger/ESP32_PCB 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 ESP32-C6 design in my own project?

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

Can I test firmware for the ESP32-C6 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.
