KeyTestBox: common questions

What microcontroller does the KeyTestBox use?

The KeyTestBox is built around the STM32F767VIT6, from the STM32 family.

How big is the KeyTestBox PCB?

The KeyTestBox measures 198.1 × 108.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KeyTestBox?

14 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the KeyTestBox design files?

From the Brunomvsilva/KeyTestBox repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the KeyTestBox design in my own project?

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

Can I test firmware for the KeyTestBox 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.
