Two motor driver: common questions
What microcontroller does the Two motor driver use?
The Two motor driver is built around the TEENSY4.0, from the NXP family.
How big is the Two motor driver PCB?
The Two motor driver measures 101 × 60 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Two motor driver?
52 components, from 24 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 Two motor driver design files?
From the owhite/simpleFOC_board 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 Two motor driver design in my own project?
The repository has no license, so all rights stay with owhite. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Two motor driver without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
