Still, make do with the hard and thick shielded twisted pair for remote signal-transmitting? And even drop the baud rate again and again just for transmission stability? Now get rid of these problems by using this Gravity: UART Fiber Optic Transceiver Module from DFRobot! With complete electrical isolation for preventing electromagnetic interference, this module runs at 2000000 baud at any time within a distance of up to 10km. Besides, it features lightning protection and can share cable trunking with strong power. Also, users can use it with a passive optical splitter to realize one-to-many star networking.   Two transceiver modules for only half the price of shielded twisted pair can provide users with long-distance & interference-free fiber-optic communication, good value for money!

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
