Fiber Opt click 5V (MIKROELEKTRONIKA)

Fiber Opt click™ 5V is a compact and easy solution for adding fiber-optic communication to your design. It features IF-D91 fiber-optic photodiode, IF-E97 fiber-optic LED diode as well as two operational amplifiers. Provided plastic optic connectors feature an internal micro-lens and a precision-molded PBT housing to ensure efficient optical coupling with plastic fiber cable. Data rates of up to 512 Kbps can be achieved. The Fiber Opt Click™ communicates with the target MCU via UART interface or directly through the GPIO pins depending on the position of the J1 and J2 SMD jumpers. UART position is set by default. Board is designed to use 5V power supply. Click here for 3.3V version.
