If so, is it possible to order it unassembled?
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.
Can this relay be connected to a Arduino Uno to regulate power to a 110V device ?
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
Is there a circuit diagram for this product? At present there isn't one on the wiki page.
