  • I've been using this board for a little while in a project, and i've noticed that it seems to function just fine without any power applied to the logic (VCC) pin. So far, I haven't noticed any issues, but i'm curious if anyone has any thoughts on whether or not this is a good/bad idea? Motor operation seems to be unaffected with it powered or not. Also, spec sheet says that the TB6612FNG has a VM in minimum of 4.5 V, currently i'm supplying it with 2 AAA batteries (right now, at 2.6 V) and nothing on the VCC line, am I going to fry this thing?

No public wish lists :(
