CloudSmoker: common questions

What microcontroller does the CloudSmoker use?

The CloudSmoker is built around the ESP32-C3-WROOM-02U-N4, from the ESP32 family.

How big is the CloudSmoker PCB?

The CloudSmoker measures 70 × 70 mm, has 4 copper layers and is 1.6182 mm thick.

How many components are on the CloudSmoker?

56 components, from 26 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 CloudSmoker design files?

From the cwgstreet/cloudSmoker 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 CloudSmoker design in my own project?

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

Can I test firmware for the CloudSmoker 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.
