Relay Shield (ie 5V Quad Relay Module) is a small current signal control power equipment commonly used electronic module, enabling high-power single-chip control devices are widely used in SCM system to make smart home project; and can be directly plugged into the use of various types of motherboards, eliminating the patch cable troubles.

1. Standard Shield interfaces and shape
2. Can continue to stack other expansion boards
3. 3 M3 screw positioning holes for easy installation
4. High Drive (5V or 3.3V) normally open contact closure
5. Onboard relay indicator (red)
Special Note: When using the board connected to it, because USB interface is extremely high, should avoid green terminals are shorted its shell.
Relay Shield Interface:
Relay: sky- 5V DC relay , model HJR-4102-L-5V, which Relay1 behalf of the 1st relay , the other and so on.
Power Interface : 5V DC power interface
Indicator: four lights are red when the relay is driven high , the corresponding indicator will light up .
Relay Terminals: Terminal high-power , high-current high voltage can be connected to the device . The 1st foot ( i.e. NOx) is a normally open pin , NCx pin is normally closed , COMx is common, i.e., when the relay is not driven , NOx and COMx open between two pins , NCx and COMx connection ; When the relay (x) control signal pin is high drive relays , NOx and COMx connection open between NCx and COMx.

    All functions are normal
    The terminals strongly protrude from the bottom of the board, touch the usb socket on the uno. and the module does not stand completely. I had to waste the protruding part of the contacts and everything got up as it should. On the usb socket glued to the insulating tape. The size of the board is the same with uno. Match 3 mounting holes, 4th is missing due to the installed terminal block. The payment is satisfied. I recommend
