Product Highlights
- Standard interface that can be controlled directly by microcontroller (aduino , 8051, avr, pic, dsp, arm, arm, msp430, ttl logic)
- Indication led's for relay output status
- 5v relay interface board, and each one needs 15-20ma driver current
- Control dc or ac signals can control the 220v ac load
- Useful to control a motor, a led strip, or any other module using iduino. how to use it: just connect a digital output of your iduino to your relay module, and you can control a power-demanding appliance with the digital signal provided by your iduino.
