# RS-485 Breakout Board for XIAO and QT Py (Component) ## Description The Seeed Studio RS-485 Breakout Board is a versatile RS-485 expansion designed for all Seeed Studio XIAO development boards. Equipped with the TP8485E transceiver IC, this breakout board efficiently converts UART serial streams to RS-485 signals. Operating as a half-duplex transceiver, the TP8485E enables unidirectional communication, spanning distances of up to 1200 meters. This breakout board is engineered for efficiency, consuming power from a single 5V or 12VDC power source. Its RS-485 output is facilitated through 3-pin terminals for both signal wires and power connections. These features collectively make it an ideal choice for robust data transmission across extensive distances and in challenging, high-noise environments. ## Component Details - **Owner:** seeedstudio - **Created:** 1/2/2025 - **Last Updated:** 1/2/2025 - **Visibility:** Public - **Manufacturer Part Number:** 113991354 - **Product Info Url:** https://www.seeedstudio.com/RS485-Breakout-Board-for-XIAO-p-6306.html - **Used in:** 3 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
