This motherboard is not working. This is from world's one of the most advanced tennis ball machines out there. This board is not working, I replaced it with new one because no knowledge and time to keep repairing it.This board started to behaving weird after I had some training session under a little of rain. It started to act randomly weird and then stopped working at all.There are mosfets and/or transistors burned(please see pictures, or ask for high resolution photos and I'll send them). For any knowledgeable technician, this should be(hopefully) a quick fix. See photos , make decisions.... Sold as is, as 100% not working, with few burned chips, for parts, as is.
