If so, is it possible to order it unassembled?
Sorry , it can't , we do not sell it as a kit.
Hi What is the difference between this unit and a grove relay you sell (at http://www.seeedstudio.com/dep.... I am trying to connect it to a arduino uno.
Just the difference of interface method ,grove-relay with grove interface, this one with twig interface.
Can this relay be connected to a Arduino Uno to regulate power to a 110V device ?
Yeah,it is.It can be power to 110V device ,current limit 10A.
The relay doesn't switch reliably with Vcc at 3.3V -- which is to be expected, it's a 5V relay. Can I connect a 3.3V atmega output pin directly to the control input of this board without damaging the atmega when Vcc for the relay board is at 5V, or do
It's ok, and it doesn't need level translation.
Is there a circuit diagram for this product? At present there isn't one on the wiki page.
