RS-485 Breakout Board – SparkFun BOB-10124

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.


  • 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


  • Length: 25.4mm (1.0″)
  • Width: 22.9mm (0.9″)
