Key Features​

  • Differential Signal Transmission: Supports robust communication over long distances (up to 1200m) and in noisy environments.
  • Bidirectional Communication: Enables two-way data transfer using a single twisted pair of wires.
  • Voltage Range: Operates with a supply voltage of 5V, ensuring compatibility with most microcontroller systems.
  • Compact Design: Dimensions of 38 x 22 mm, making it suitable for space-constrained applications.
  • High-Speed Communication: Supports data rates up to 20 Mbps, making it ideal for high-speed industrial applications.
  • Onboard ESD Protection: Protects against electrostatic discharge, ensuring reliable operation in harsh environments.
  • Low Power Consumption: Requires only 120μA to 500μA of current, making it energy-efficient.

This breakout board is based on the SN65176BDR transceiver IC, which meets or exceeds the requirements of ANSI TIA/EIA-422-B and TIA/EIA-485-A standards. It is designed for multipoint transmission on long bus lines and includes features like thermal shutdown protection, current limiting, and wide positive/negative input/output voltage ranges.
