H730duino: common questions
What microcontroller does the H730duino use?
The H730duino is built around the STM32H730ZBT6, from the STM32 family.
How big is the H730duino PCB?
The H730duino measures 101.6 × 53.3 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the H730duino?
109 components, from 41 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the H730duino design files?
From the martinribelotta/h730duino repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the H730duino design in my own project?
Yes, under the terms of its MIT license, which martinribelotta chose for the repository.
Can I test firmware for the H730duino 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.
