H7value: common questions

What microcontroller does the H7value use?

The H7value is built around the STM32H750VBT6, from the STM32 family.

How big is the H7value PCB?

The H7value measures 63.5 × 73.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the H7value?

60 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the H7value design files?

From the martinribelotta/h7value repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the H7value design in my own project?

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

Can I test firmware for the H7value 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.
