The RS-485 Module allows you to communicate over RS-485 bus using MODBUS or your custom protocol. Many devices could be connected to the single RS-485 bus and exchange data. This module also contains DC/DC converter so it can power the node. Supported input voltage is 5 - 28 V.
This module has low-power mode when data receiving is not enabled. This way RS-485 node could work for long time just from batteries.
Only I2C pins are used thanks to I2C to UART converter SC16IS750IPW
