	This is a breakout board for the RS-485 transceiver IC, which will convert a UART serial signal to RS-485. This chip is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 2.5Mbps. This board requires a very low amount of power and can operate from a single +5VDC supply.		This is a breakout board for the RS-485 transceiver IC, which will convert a UART serial signal to RS-485.

==Overview==
This is a breakout board for the RS-485 transceiver IC, which will convert a UART serial signal to RS-485. This chip is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 2.5Mbps. This board requires a very low amount of power and can operate from a single +5VDC supply.

This breakout board includes the SP3485 RS-485 transceiver, filter capacitor. We've broken out the RS-485 output to three different connections: (1) an RJ-45 connector, (2) a 3-pin 3.55mm screw terminal, and (3) a 3-pin 0.1" pitch header

==Features==
*Fully equipped with SP3485 RS-485 transceiver and supporting components
*Operates from a single +5V supply
*Interoperable with +5.0V logic
*RS-485 input/output broken out to RJ-45 connector, 3.5mm screw terminal, and 0.1" pitch header
*Driver/Receiver Enable connected to RTS line
*-7V to +12V Common-Mode Input Voltage Range
*Allows up to 32 transceivers on the serial bus
*Driver Output Short-Circuit Protection

==Usage==
Here is an example below illustrates how to transimit and receive data via RS-485 signal.
