  • As long as you don't have a microSD card in the microSD slot, the fact that you have a wire going there that is energized is irrelevant. You don't need to bend any pins. Just don't put a SD card in the slot. You can't "enable" something that's not physically connected. Commented Apr 22, 2014 at 0:40
  • Note: there is a voltage translator in there too, but it doesn't matter if it's not connected to something at both ends, so you can ignore it. Also, it doesn't "switch the SD card on/off" anyways. It's a chip-select line, not a power line. It just controls the bus-arbitration electronics in a already powered on SD card.

  • @Connor I know that you probably don't have to do that, IMO it's more of a "best practice" thing. I'm editing to clarify my post. It also prevents accidental problems if you were to plug in a SD card forgetfully. Commented Apr 22, 2014 at 0:47
  • If you don't have to do it, and it involves damaging one of your devices somewhat, I'd qualify it as "worst practices", rather then "best" practices. It's not like you can damage anything anyways, the level translator has limited drive capability. Commented Apr 22, 2014 at 1:07
  • Thanks guys, the but what about pin 7? it's used in both shields, and unlike the pin 4, it's something that i'll use, because it's used for the "initialization of the communication protocol between the shield and Arduino WiFi" Commented Apr 22, 2014 at 3:47
