RS-485 Breakout Board: an embedded 10-Mbps transceiver

The RS-485 Breakout Board by Sparkfun was specially designed for more easily connecting and using the SP3485 RS-485 module, a unidirectional transceiver acting as an UART to RS-485 adapter. It allows you to transmit your UART data via an RS-485 connection at speeds of up to 10 Mbps, all with a 3.3V power supply.

UART/RS-485 transceiver breakout: 3 possible types of connection

Not only does this breakout board have a SP3485 RS-485 transceiver module, but it also offers 3 different types of connection:

  • RJ-45 connector
  • 3.5 mm 3-pin screw terminal
  • 2.54 mm 3-pin header
