Opto 2 click is a galvanic isolator Click board™, used to provide an optical isolation of sensitive microcontroller (MCU) pins, when operated by external signals. TLP2770 opto-isolation elements (optocouplers) can be driven with a very low current, down to 1.3mA (min). A choice of high-speed optocouplers allows Opto 2 click to be used on communication lines, with up to 20 Mbps data rates. This Click board™ can be used to provide an optical isolation when there is a requirement for a high reinforced isolation between the external signal lines and the controller logic with a MCU such as in PLCs or similar applications
