SmartElex USB to RS-485 Converter

This SmartElex USB to RS-485 Converter combines an SP3485 RS-485 transceiver with an FT232RL USB UART IC, allowing you to easily convert USB data to RS-485. The SP3485 is a half-duplex transceiver, meaning it can only send or receive data at one time, but it supports transmission speeds of up to 10Mbps. The FT232RL's TXDEN pin is connected to the transmit and receive enable pins of the SP3485, controlling the RS-485 transceiver's transmission mode. Once the appropriate drivers are installed, the FT232RL appears as a virtual COM port, with driver support for Windows, Mac, and Linux. This breakout board features the SP3485, FT232RL, TX/RX/RTS indicator LEDs, a Mini-B USB connector, filter capacitors, and other essential components as outlined in the schematic. The RS-485 output is accessible via three options: an RJ-45 connector, a 3-pin 3.55mm screw terminal, and a 3-pin 0.1" pitch header, though none of these output connectors come pre-installed.
