What is this?
2 Channel Relay Module Relay Board Arduino Relay Module. With Optocoupler allows a wide range of microcontrollers. Such as Arduino, AVR, PIC, ARM with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs. 4 – channel relay interface board , and each channel needs a 15-20mA driver current. It can be used to control various appliance
What can I build with it?
- Beginner robots, line followers, and classroom kits
- Sensor experiments with clear pin headers
Compatibility notes
1-Channel Relay Module: 3.3–5V typical domain. Confirm active-high/low module. Mains wiring requires qualified safety practices.
Known pins (verified catalog): VCC, GND, IN
Specifications
- 2 Channel Relay Module Relay Board Arduino Relay Module With Optocoupler
- High-level trigger refers to using the anode voltage at the VCC connection way of a trigger. And triggers the end when the trigger side has the positive voltage or to trigger voltage when the relay is off.
- Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
- Exellent quality and best price
- I am really very satisfied with the service!
- Order received on time
- Excellent product. I have been using this relay module with ESP8266 to replace a defrost timer on my refrigerator for over a year. Although a single relay is needed, its nice to have a backup in case first one fails.
