Teapot: common questions

What microcontroller does the Teapot use?

The Teapot is built around the STM32L052K6T6, from the STM32 family.

How big is the Teapot PCB?

The Teapot measures 23 × 57 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Teapot?

48 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Teapot design files?

From the cillian64/teapot repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Teapot design in my own project?

The repository has no license, so all rights stay with cillian64. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Teapot 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.
