Gravity: UART Fiber Optic Transceiver Module
95 units will be available shortly.
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!
Interface & Pin
Pinout
| Name | Description |
| Gravity: UART | UART interface, connect to MCU or sensor |
| PWR LED | Power indicator, turns ON when powered on |
| SD LED | Indicator for optical fiber disconnection, which lights up when the fiber optic disconnection is detected |
| TX LED | Indicator for fiber optic transmitting, which blinks when transmitting signal |
| RX LED | Indicator for fiber optic receiving, which blinks when receiving signal |
| SC Fiber Optic Interface | Connect to SC fiber optic interface |
SD LED can not show all the fiber disconnections or unstable transmissions. Please use a red pen, optical power meter and other tools to check error when a connection problem occurs.
