Breakout Board mit dem SP3485 RS-485 Transceiver.
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.
