Hotplate: common questions

What microcontroller does the Hotplate use?

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

How big is the Hotplate PCB?

The Hotplate measures 60 × 45 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Hotplate?

74 components, from 37 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 Hotplate design files?

From the Keyaan-07/Hotplate 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 Hotplate design in my own project?

Yes, under the terms of its MIT license, which Keyaan-07 chose for the repository.

Can I test firmware for the Hotplate 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.
