Schottky Diode D1
Schottky Diode D1
What is the function of Schottky Diode D1 (MBR0520) on the Super Pro board. The diode on my board seems to be open, and I can no longer power my board through J4. Can I simply jumper around that diode, my source is regulated 7.0 Volts?
Re: Schottky Diode D1
D1 prevents connecting an incoming power supply from being connected backwards. That is a pretty beefy diode, if it had not blown you probably would have completely destroyed the board. So you should think about what you were connecting up when that part failed.
Re: Schottky Diode D1
I mis-mated the the Arduino J1 power pins. I probably connected +5V to ground. The 7805 survived, but D1 is gone. I'll just jumper it out. I have a board that plugs into the Super Pro, but it's a 0.1x0.1 perf board, and the mating is not perfect with the Arduino. I have to live with that until I get a PC board made.
Re: Schottky Diode D1
I would really like to get a 0.1"x0.1" perf board with the 6, 6, 8, & 6 Arduino pins. The 0.1x0.1 area should be connected in a matrix, and lands should connect to the Arduino pins.
I could eliminate this mating board with a redesign of the 3rd board in the stack.

Re: Schottky Diode D1
All of our boards connect the Arduino mistake offset pins to a parallel 0.1 x 0.1" pattern, so you can use an off the shelf perf board.
Re: Schottky Diode D1
Which off the shelf perf board do people usually go for btw?
I need one of these awesome recurve bows for sure.
Re: Schottky Diode D1
You use to be able to pick one up at the local Radio Shack, but that is no more. Fry's has a wide assortment, or online at SparkFun, and others, maybe even eBay.
Re: Schottky Diode D1
If you can't find something on eBay, you night consider building a cutom board, With KiCAD tools (free) and OSHpark fabrication it is pretty cheap.
