Seeed Relay Shield + WiFly Shield + Arduino

Hi Guys
I have an Arduino Uno, WiFly Shield and Seeed Relay Shield which I’d like to use together (controlling 240VAC switching via Wi Fi).
The WiFly Shield uses pins RX, TX, Vin, Gnd, pin 10, pin 11, pin 12 and pin 13
The Seeed Relay Shield uses pins 4-7
Does this mean all three units with be interoperable?
If I stack the WiFly Shield on the Arduino I’ll have to break out pins 4-7 to the Relay Shield, what other pins need to be connected, just GND? And an external 9v power supply?



Yes, I think you are right. :slight_smile:
