Motor: common questions
What microcontroller does the Motor use?
The Motor is built around the STM32F031K6U6, from the STM32 family.
How big is the Motor PCB?
The Motor measures 45 × 45 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Motor?
49 components, from 37 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 Motor design files?
From the mkramar/dizzyrobot repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Motor design in my own project?
The repository has no license, so all rights stay with mkramar. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Motor 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.
