Description: 1. Overview: An USB 2.0 to TTL RS485 Serial Converter Adapter FTDI Module (FT232FRL SN75176) is a versatile device that enables bidirectional communication between computers and RS485 bus-based systems using standard TTL levels. It employs an FTDI FT232RL chip for USB 2.0 interface and a MAX485 (or equivalent SN75176) driver IC for RS485 functionality. 2. Features: This converter offers full-duplex communication with a data rate of up to 115 kbps, making it suitable for various applications such as industrial automation, building control systems, and telemetry projects. It includes an integrated LED indicator for power (Vbus), status (RX and TX), and bus activity (A and B). 3. Flexible Data Modes: The converter supports different communication modes like auto-addressing, manually addressing, or broadcast mode, allowing users to customize their application based on requirements. 4. Dynamic Power Supply Management: The USB 2.0 interface can deliver power (up to 500mA) to the RS485 bu
