KNACRO 3.3V UART Serial to RS485 SP3485 Transceiver Converter Communication Module

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: an RJ-45 connector, a 3-pin 3.55mm screw terminal, and a 3-pin 0.1" pitch header; none of these output connectors come populated.
