Main board: common questions
What microcontroller does the Main board use?
The Main board is built around the STM32F429VET6, from the STM32 family.
How big is the Main board?
The Main board measures 100 × 74 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Main board?
125 components, from 35 distinct parts. The full bill of materials is listed on this page.
Where can I download the Main board 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 Main board 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 Main board 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.
