The Grove RS-485 allows your Arduino to connect with the RS-485 device easily, you just need to plug and play.
RS485 is a cost-effective solution in serial communication, it can be used to the data rate at 10Mbit/s or distance up to 1200m at a lower speed.
- Supply voltage: 3.3V/5V
- Interface: UART
- Data Signaling Rate: Up to 10Mbit/s
