5VDC 10A Single Channel Relay Module compatible with arduino
RM5.00DescriptionNote: From February 2020 onwards, the module comes with a logic low circuit.
The Relay breakout board is a convenient board to be used with 5V microcontrollers such as SK40C, SK28A, Arduino, SKds40A, SK18B. You can easily use 5V signal to control the relay. Three inputs:
- VCC = 5V is needed
- GND = Common Ground, 0V
- IN = Control signal need to be
5V0V to activate the Relay (Active Low)
The relay terminals (COM, NO, and NC) are brought out using a 3-way screw terminal. On-board relay is rated at 10A. It can be used in many applications: controlling high voltage, high current loads such as motor, solenoid valves, lamps, and AC load. It also comes with 2 LEDs to indicate the status power (VCC) and the status of the relay.
Note: This is an
active-highactive-low device, which means logichigh (5V)low (0V) at pin IN will trigger the relay. -
Ethernet Shield V2.0
RM30.00The Ethernet Shield V2.0 is finally released and supports both Mega 1280 and 2560. Besides, it also supports micro SD card read/write. The ethernet shield is fully functional now. The V2 Ethernet Shield is fully compatible with Ardunio Ethernet Shield. With the offical ethernet library, you can do exactly the same thing as the original one. But at a more affordable price.
