RioRand(TM) D213 Opto-isolator Breakout Board for your microcontroller Board

The Opto-isolator Breakout Board which uses the ILD213T optoisolator and discrete transistors to correct the logic. Comes with two channels can help you to connect digital systems (like a 5V microcontroller) to a high-voltage or noisy system. It electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has two LEDs and two photodiodes built-in. This allows the low-voltage side to control a high voltage side. This board will isolate the systems, creating a type of electrical noise barrier between devices.You can use this board to allow a microcontroller control servos or other motors that use a higher voltage than the TTL logic on the (3.3V or 5V) micro, and may cause electromagnetic interferance with our system as the motors turn on and off.
