The KiCad project lives in the quasiengineer/usb-pd-mch-hotplate repository on GitHub; these links point at the commit this page was built from.

Usb pd mch hotplate: common questions

What microcontroller does the Usb pd mch hotplate use?

The Usb pd mch hotplate is built around the STM32G431CBTx, from the STM32 family.

How big is the Usb pd mch hotplate PCB?

The Usb pd mch hotplate measures 62.5 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Usb pd mch hotplate?

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

Where can I download the Usb pd mch hotplate design files?

From the quasiengineer/usb-pd-mch-hotplate repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Usb pd mch hotplate design in my own project?

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

Can I test firmware for the Usb pd mch hotplate without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
