1 Channel Relay Module Board Shield 5V/12V

1. This module complies with international safety standards, and the control area and the load area have isolation slots;
2. using genuine relays;
3. with power and relay action instructions, the light is closed, the light is off;
4. When there is a signal at the signal input end, the common end and the normally open end will be turned on;
5. can be used as a microcontroller development board module, can be used as home appliance control;

The high level trigger refers to the trigger mode of the voltage between the signal input terminal and the ground, which can be understood as a way to trigger the short circuit of the signal input terminal and the VCC positive terminal;
Low-level triggering refers to the triggering mode of the voltage between the signal input terminal and ground is OV, which can be understood as a way to trigger the short circuit of the signal input terminal and the GND negative terminal.
