## Description

3v Relay Board for Raspberry Pi Arduino Relay Module 1 Channel Opto-Isolate High Level Trigger for IOT ESP8266 Microcontrollers Development Board

## Features

- 【1 Channel Relay Module】- This Relay Board provides a single relay that can be controlled by any 3V/3.3V digital input from your microcontroller IO.
- 【Main Specification】- The 3v Relay 1 Channel power switch module compatible with 10A 250VAC and 10A 30VDC load.4pcs * 2.5 mm Fixed Bolt Hole.
- 【Adopted Optocoupler Isolation】- 3V/3.3V power relay module supports photocoupler isolation control and dual power supply input ensure high anti-interference ability. Fast response time less than 20ms and long life time up to 100,000 times snap action with diode freewheel protection.
- 【Jumper Caps】You can select whether the relay and the signal use the same power supply or not by removing the jumper caps on the pins. And It is better to share the same power supply, because that is more convenient for using.
- 【Wide Application】- These 3v relay board works well with Arduino/ ARM /PIC /AVR /MCU/Raspberry/CNC machine/ PS4/3.3V /NodeMCU/IOT/ ESP8266 module etc.
