Description

This is the newest revision and fixes issues with the last board. This
breakout board pairs an SP3485 RS-485 transceiver with an FT232RL USB
UART IC to convert a USB 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.

The TXDEN pin of the FT232RL is connected to the transmit and receive
enable inputs of the SP3485, this line is used to control the
transmission mode of the RS-485 transceiver. With the proper drivers
installed, the FT232RL will enumerate as a virtual COM port; the
drivers are available for Windows, Mac and Linux.

This breakout board includes the SP3485, FT232, TX/RX/RTS LEDs,
Mini-B USB connector, filter capacitors, and other components shown on
the schematic. We've broken out the RS485 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.
