This module interfaces an Arduino or similar microcomputer to RS-485. RS485 is used for Serial Communications over longer distances than direct RS232 or TTL, and supports multiple units on the same bus (Multi-Drop). The driver slew rates of the MAX485 is not limited, allowing them to transmit up to 2.5Mbps.
- Multiple Units can be connected to the same RS-485 wiring.
- All Chip pins are brought out for proper controls
- Working voltage: 5V
- Board size: 44 (mm) x14 (mm
