Summary

Grove-connected RS485 to TTL conversion unit enabling robust long-distance serial communication with configurable timing and break signals.

Description

The M5Stack RS485 to TTL Unit component provides bidirectional conversion between RS485 differential signaling and TTL-level serial communication. It features configurable baud rates, send/receive timing control, and break signal generation for robust industrial communication. The Grove interface ensures easy connectivity to M5Stack systems, while the RS485 protocol supports long-distance communication with noise immunity. Typical applications include industrial automation, building control systems, and long-range sensor networks.
