Common Control: common questions
What microcontroller does the Common Control use?
The Common Control is built around the STM32F446RETX, from the STM32 family.
How big is the Common Control PCB?
The Common Control measures 110 × 120 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Common Control?
219 components, from 56 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 Common Control design files?
From the Tomoshibi-technology/Tomoshibi_Circuit 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 Common Control design in my own project?
Yes, under the terms of its MIT license, which Tomoshibi-technology chose for the repository.
Can I test firmware for the Common Control 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.
