Review: Brilliant items and simplifies motor control - I had a plan in mind to control a lot of servos from one arduino. My initial tests using individual outputs on the arduino quickly became a jungle of wires and lots of code. This motor driver though is amazing. Just a few connections to the arduino itself and I quickly had an array of 8 servos running. The external power is a must and for this I purchased some open ended USB-C sockets. Really really pleased with this, and you can connect a number of them together for even more motors if needed.
Review: Great - Good quality item
