Why would someone put all that time into researching what component failed on a cheap little board like that is my question, hell, just pm me your shipping info and i will send you a good working board.
Because man, I just don't have an extra $30-40 to spend on a new driver, I have almost nothing available funding for hobbies and it would be a easier for me to spend time doing a little research and spending $2 than it would to try to come up with $40 for one of those new BlackBuck 6amp drivers.
