4 Channel relay Module compatible with arduino
RM20.00Relays are always good to have especially for electronics projects. Relay itself offers two main benefits:
- Isolation of low voltage system against high voltage system, example 5VDC and 240VAC
- Allow electronics with low voltage to control high power load, example from Arduino to AC light bulb.

9V Battery Holder and Connector
RM3.00DescriptionThe Battery Holder is suitable for 9 Volt Batteries. The pro of having this battery holder is that it allows you to switch off power for Arduino without having to remove the DC barrel plug each time. This Battery Holder has an easy-remove sliding cover. The removable battery cover is at the opposite side of the ON/OFF switch.

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.
