Mainboard v13: common questions
What microcontroller does the Mainboard v13 use?
The Mainboard v13 is built around the STM32H743ZST, from the STM32 family.
How big is the Mainboard v13 PCB?
The Mainboard v13 measures 80 × 85 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Mainboard v13?
118 components, from 45 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mainboard v13 design files?
From the TIGERs-Mannheim/electronics repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Mainboard v13 design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Mainboard v13 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.
