MotionControl: common questions
What microcontroller does the MotionControl use?
The MotionControl is built around the ATSAMD21J18A-A, from the Microchip SAM family.
How big is the MotionControl PCB?
The MotionControl measures 180 × 80 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MotionControl?
191 components, from 46 distinct parts. The full bill of materials is listed on this page.
Where can I download the MotionControl design files?
From the meowmeowahr/KevinbotV3-MotionControlHardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the MotionControl design in my own project?
The repository has no license, so all rights stay with meowmeowahr. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MotionControl without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
