While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino shield.

The project uses an Arduino Uno R3, Arduino Mega 2560, Arduino CNC Shield V3 GRBL, Stepper Motor Driver A4988 and Arduino L293D Motor Shield together with a couple of wooden wine boxes to create a ...

The High Power H-Bridge Motor Shield for Arduino is equipped with built-in current sensing utilizing the ACS712, and is capable of driving any DC motor up to 15Amp.

Enrico shows how his Infineon TLE94112EL motor controller shield can be put to work through a simple Arduino sketch.

In turn, since he needed an easy way to program the flash memory which holds the software to run on the Z80, he used an Arduino Mega as a debugger, making the SBC an Arduino shield itself.

The 1Sheeld, a single shield that lets you replace all of those other shields with your smartphone. Today, that project went up on Kickstarter and almost immediately destroyed its fundraising goal.
