Hi Ernest.The Maximum current is 15A,but the safe current may not more 8A.

It *clearly* says 7A 250VAC right on the relay.

Hey David.The pin-4,5,6,7 are all output pins(more information you can refer to the schematic which you could download it from the wiki:http://www.seeedstudio.com/wik...

Hi,this shield can use with the seeeduino ethernet,you may have uartbee better,and use uartbee to connect ethernet.just try and enjoy~

Hi,It seems difficult two Relay Sheilds and connect them both somehow to one Arduino.but I think you can use 1 relay shield and 4 grove - relay.try it,you can run 8 relays~~

Hi,It seems difficult two Relay Sheilds and connect them both somehow to one Arduino,but you can jump the line to connect the arduino.I think you can use 1 relay shield and 4 grove - relay better.with nice day~

Shield is powered through Arduino with additional power line to USB.

Hi,sure,Here the schematic is!--------http://www.seeedstudio.com/wik... a happy day~

Hi, Switching voltage is Max to 35VDC.

Hey Edward, yes. It is compatible with Arduino Yun. The Yun has a large RJ45 port. But the pins of the shield still can be inserted into the groove. :) I have just tested.

The pin blocks are not connected to the board. To use the board, I have to solder them on first. Is that how these come or is mine defective?

Are you saying the xbee digital output bins on the xbee shield are mapped directly to the control pins for the relays (or could you jumper it that way)? Or would you need an arduino to pair the two together?

Hi,Sorry ,you can not stack the 2.8'' Touch shield on top of this shield.if you use the tft touch shield ,you only get the pin -3,8,9and A4,A5 free.with a happy day~

Hi~of course,we suggest user:Do not operate voltage more than 35V DC. It will be dangerous. and you can find other cautions in our relay shield wiki.---http://www.seeedstudio.co

Yes, it can support 240VAC, but should be no more than 7A.
