Olimex MOD-RS485

RS485/RS422 converter module with UEXT

Using this module you can easily connect our development boards (that feature UEXT connector) to industrial networks with a RS485 interface, metering instruments etc.

Olimex MOD-RS485 is a small module board created with the help of an ADM3483ARZ - a low power, differential line transceiver, designed to operate using a single 3.3 V power supply, for half-duplex communication. This module can be used to convert RS232 signals into RS485 signals. The board comes with a 10 pin cable for the UEXT, via which it can be connected to each of our development boards with a UEXT on it. This module is an excellent choice for conveying information over long distances, allowing an error-free data transmission at data rates up to 250 kbps.

The module uses UART interface and two control pins to establish connection to the host board (all required signals available at the UEXT header).
