just an example driver there are a lot more of them Microchip TC1410 On 3/5/2015 2:38 PM, g...@sensa.io wrote: > I did this setup with an LED strip, MOSFETs, and a separate 12V power > supply: http://forums.adafruit.com/viewtopic.php?f=8&t=69691&p=353076 > See 5 posts down of a picture. > > This setup has apparently fried 2 of my Beaglebones. > I tested the gate pins on the MOSFETs (which were the only thing > connected to the Bone) and they were only reading about 200mA. > > The Adafruit customer support says they don't think this would be > capable of frying the board. > > I've been searching trying to see if somehow this tripped a fuse or > something on the Bone. > > One of my Bones the power light comes on, but it won't boot (Rev B). > On the other (Rev C), the power light flickers and then goes off and > nothing happens. > > Any ideas? > -- > For more options, visit http://beagleboard.org/discuss > --- > You received this message because you are subscribed to the Google > Groups "BeagleBoard" group. > To unsubscribe from this group and stop receiving emails from it, send > an email to beagleboard+unsubscr...@googlegroups.com > <mailto:beagleboard+unsubscr...@googlegroups.com>. > For more options, visit https://groups.google.com/d/optout. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
