This board was created to evaluate the operation of the TI DRV8212P in driving common N20 geared DC motors.
Certain considerations are required dependent on the selected motor and sensing features. By default, the VM (V_motor) and VCC (V_io) are tied together via the bridged pad. This is for operation of the motor at the same voltage of the controller mcu. If independent nets are to be used, the bridge must be cut and VM and VCC must be independently provided via the input header pins.
Additionally, DRV8212P provides load sensing capability via a sense resistor between the ICs ground and the board ground. The value of R_SENSE is dependent on the requirements of your application and is left to the user to calculate.

Questions
How big is the Drv8212p eval PCB?
It measures 46 × 26 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Drv8212p eval use?
24 parts, built around the DRV8212PDSG. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Drv8212p eval KiCad files?
From the ninteru/drv8212p_eval repository on GitHub, at the commit this page was made from: the board is drv8212p_eval.kicad_pcb and its schematic drv8212p_eval.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Drv8212p eval design in my own project?
Its repository states no licence, so its author keeps all rights: ask ninteru before reusing the design.
