M5Stack ATOMIC RS485 Base

The M5Stack ATOMIC RS485 Base is a highly functional TTL-RS485 converter, specifically designed for use with M5Atomic. This module facilitates TTL and RS485 level conversion and supports the standardized RS485 communication, which is widely used in the industry. It enables multi-point communication systems and is ideal for application equipment that needs to communicate and be controlled over RS485. An integrated DC/DC voltage regulator chip in the ATOM RS-485 directly converts 12V voltage from RS485 into 5V to power the M5ATOM, eliminating the need for a separate power supply.

Features:

• Compatible with ATOM Matrix/ATOM Lite/ATOMS3/ATOMS3 Lite.
• Uses the SP3485EE chip for level conversion.
• Integrated DC/DC converter.
• Supports multi-point communication.
• Application examples:
• Multi-point communication over RS485.
• Usage as an industrial control node.
