SparkFun Transceiver Breakout - RS-485

This is a breakout board for the SP3485 RS-485 transceiver IC which will convert a UART serial stream to RS-485. The 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. This board requires a very low amount of power and can operate from a single +3.3VDC supply. This 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 0.1" pitch header; none of these output connectors come populated.
