SparkFun Transceiver Breakout - RS-485

The SparkFun Transceiver Breakout - RS-485 is a comprehensive solution for converting a UART serial stream to RS-485. This product features the SP3485 RS-485 transceiver IC, a half-duplex transceiver that allows for one-way communication at speeds of up to 10Mbps. The board operates from a single +3.3VDC supply, ensuring low power consumption.

The SparkFun RS-485 breakout board is fully equipped with the SP3485 RS-485 transceiver, a filter capacitor, and other essential components. The RS-485 output is broken out to three different connections: an RJ-45 connector, a 3-pin 3.55mm screw terminal, and a 3-pin 2.54mm pitch header. However, keep in mind that these output connectors do not come populated.

Some of the key features of this product include interoperability with +5.0V logic, the ability to connect up to 32 transceivers on the serial bus, and driver output short-circuit protection. The board also boasts a -7V to +12V common-mode input voltage range and driver/receiver enable connected to the RTS line. With its compact size of approximately 2.29cm x 2.54cm, this breakout board is an excellent choice for projects requiring RS-485 communication.

The SparkFun Transceiver Breakout - RS-485 is not only versatile but also reliable. It provides an efficient way of converting UART serial streams, making it ideal for a wide range of applications. Whether you're working on a DIY project or a professional assignment, this product offers a reliable and efficient solution for your RS-485 communication needs.
