Description:

This is a breakout board for the SP3485 RS-485 transceiver IC, which will convert a UART serial stream to RS-485.
SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps.
Board requires a very low amount of power and can operate from a single +3.3VDC supply.
Breakout board includes the SP3485 RS-485 transceiver, filter capacitor, and other components shown on the schematic.
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 2.54mm pitch header; none of these output connectors are supplied.
