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. https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2011-05-01 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2016-04-01 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2016-04-04 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2016-11-25 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2016-11-27 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2016-11-28 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2016-11-29 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2016-12-09 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2016-12-13 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2017-03-31 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2017-04-04 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2017-11-24 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2017-11-28 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2018-05-05 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2018-05-11 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2018-05-15 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2018-10-30 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2018-11-21 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2018-11-27 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2019-03-15 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2019-03-19 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2019-07-04 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2019-07-09 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2019-11-29 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2019-12-03 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2020-07-24 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2020-07-31 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2022-02-21 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2025-03-24 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2025-04-11 https://elecena.pl/product/1671214/sparkfun-transceiver-breakout-rs-485 2025-05-05
