MotorCtrl3: common questions
What microcontroller does the MotorCtrl3 use?
The MotorCtrl3 is built around the STM32F407VX-100, from the STM32 family.
How big is the MotorCtrl3 PCB?
The MotorCtrl3 measures 90 × 108 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MotorCtrl3?
279 components, from 106 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 MotorCtrl3 design files?
From the Kreyl/nute repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the MotorCtrl3 design in my own project?
The repository has no license, so all rights stay with Kreyl. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MotorCtrl3 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.
