Stencil: common questions

What microcontroller does the Stencil use?

The Stencil is built around the STM32F429VET6, from the STM32 family.

How big is the Stencil PCB?

The Stencil measures 150 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stencil?

217 components, from 57 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stencil design files?

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

Can I use the Stencil design in my own project?

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

Can I test firmware for the Stencil 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.
