Product Details
- Versatile Compatibility: This 1-channel relay board is perfect for Raspberry Pi models including Zero, Zero W, Zero WH, 2B, 3B, 3B+, 4B, as well as for Arduino, STM32, ESP32 and other platforms. Ideal for a wide range of DIY electronics and automation projects.
- Reliable Optocoupler Isolation for Raspberry Pi: Our Raspberry 1-channel relay board features advanced optocoupler isolation and level-shifting circuits. This ensures strong anti-interference capability and stable operation with both 3.3V and 5V systems, safeguarding your Pi from electrical noise.
- High Load Capacity for Raspberry Pi Relay Module: The 1-channel relay board supports up to 10A at 250VAC/28VDC for the normally open (NO) contact, and 5A at 250VAC for both NO and normally closed (NC) contacts. This makes it ideal for high-power applications and automation tasks with for your Raspberry Pi or Arduino.
- Easy Relay Status Monitoring: Equipped with a relay operation indicator LED, this Pi relay board provides clear visual feedback on the relay status. This feature makes it simple to monitor the relay's operation, ensuring your Raspberry Pi automation projects run smoothly.
- Open-source Example Programs for Raspberry Pi and Arduino: Our 1-channel relay module includes open-source example programs designed specifically for Raspberry Pi and Arduino development boards. These resources make integrating the relay board into your projects effortless and quick.
