Product Description

This is a breakout board for the SP3485 RS-485 transceiver IC from Tronixlabs Australia, which converts a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver, that can only communicate one way at a time, however it can reach transmission speeds of up to 10Mbps. This board requires a single +3.3VDC supply.

This breakout board includes the SP3485 RS-485 transceiver, filter capacitor, and other components shown on the schematic. The RS-485 output is broken out to three different connections:

  • RJ45
  • 3 pin 3.55mm screw terminal
  • 3 pin 0.1" header

None of these are populated. This board is based on the open-source design by Sparkfun. 


  • 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
