Description:
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 Arduino compatible the use of various types of motherboards, eliminating the patch cable troubles.
Module features are as follows:
- Standard Arduino Shield interfaces and shape
- Can continue to stack other Arduino expansion boards
- 3 M3 screw positioning holes for easy installation
- High Drive (5V or 3.3V) normally open contact closure
- Onboard relay indicator (red)
- Special Note: When using the Arduino UNO board connected to it, because UNO USB interface is extremely high, should avoid green terminals are shorted its shell.
Package Included:
- 1x Four channel Relay Shield 5V 4 Channel Relay Shield Module for Arduino
