This is a MOSFET driver board to enable the control of a cooling fan from a Sanguinololu board using Sprinter firmware. I have included a protection diode and suppressing capacitor which is overkill if you are using a PC/GPU brushless DC motor fan but I wanted to make this drive general purpose for use in other expansion projects and experiments.
I also considered having this made by a PCB maker using SMD's but I would probably need to order a couple of hundred units to make it worth while as its such a small circuit. I think this would be a useful prototyping gadget for Arduino projects as well as 3d printer upgrades as it could be made really small using SMD's, small enough even to tuck inside a cable sleeve. I'd love to have a bunch of these in my tool box as it would save a lot of time faffing with breadboards when you just want to try something quickly. So if anyone el
