This module allows you to create an interface between a Waspmote ecosystem and an RS232 system. The module can connect directly to Socket 0 on your Waspmote main board, or to the Waspmote Expansion Board on Socket 1.
You can use this module for either the RS232 serial communication standard or the Modbus protocol. It uses a low-power transceiver, and is guaranteed to run at data rates of 120kbps while maintaining RS232 output levels.
The module has a DB9 Male connector, and comes with a cable as shown.
