Description: 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. Spark fum’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.

 

Features:

- Fully equipped with SP3485 RS-485 transceiver and supporting components

- Operates from a single +3.3V supply

- Interoperable with +5.0V logic

- RS-485 input/output broken out to RJ-45 connector, 3.5mm screw terminal, and 0.1" pitch header

- Driver/Receiver Enable connected to RTS line

- -7V to +12V Common-Mode Input Voltage Range

- Allows up to 32 transceivers on the serial bus

- Driver Output Short-Circuit Protection

 

Dimensions: 0.9x1.0"
