Main Ctrl H7: common questions
What microcontroller does the Main Ctrl H7 use?
The Main Ctrl H7 is built around the STM32H723VGTX, from the STM32 family.
How big is the Main Ctrl H7 PCB?
The Main Ctrl H7 measures 80 × 50 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Main Ctrl H7?
146 components, from 59 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 Main Ctrl H7 design files?
From the Aiyin4Da-2/Main_Ctrl_H7 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Main Ctrl H7 design in my own project?
Yes, under the terms of its MIT license, which Aiyin4Da-2 chose for the repository.
Can I test firmware for the Main Ctrl H7 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.
