CC M7: common questions
What microcontroller does the CC M7 use?
The CC M7 is built around the STM32H743VITX, from the STM32 family.
How big is the CC M7 PCB?
The CC M7 measures 40 × 65 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the CC M7?
123 components, from 58 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 CC M7 design files?
From the OzanE1/CCM7 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 CC M7 design in my own project?
Yes, under the terms of its LGPL-2.1 license, which OzanE1 chose for the repository.
Can I test firmware for the CC M7 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.
