Description

  • Breakout board for the SP3485 RS-485 transceiver IC
  • Operates from a single +3.3V supply
  • Includes SP3485 RS-485 transceiver, filter capacitor, and more
  • RoHS compliant

The SFE UART to RS-485 converter 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. The manufacturer has 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. This product replaces the sparkfun's BOB-09505.

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: 0.9" x 1.0"
