Data received on the primary serial port is relayed to the bus acting as an RS485 interface and vice versa. UART to RS485 translation hardware (e.g., MAX485, MAX33046E, ADM483) is assumed to be configured in half-duplex mode with collision detection as described inhttps://docs.espressif...
This is a RS485 shield,especially designed for the Arduino controller board. It can easily convert the UART to the RS485. This shield integrates a standard RS485 port ,a mini RS485 port(PH2.0 interface), RS485 headers, and provides the welding areas, so it's convenient for your DIY des...

RS232/485 Shield For Arduino $15.95It is both a RS232 shield and also a RS485 Shield for Arduino. It can easily convert UART to RS232 or RS485 interface. The shield integrates DB9 connectors (female) that provide connection to various devices with RS232 interface and also provide a RS...
Modbus-RTU (Remote Terminal Unit) meansthat the Modbus protocol is used on top of a serial line with an RS-232, RS-485 or similar physical interface. It is point to point communication which means it has only one master and slave. Modbus RTU is using binary coding and CRC error checking...
Moreover, this 5V MAX485 TTL to RS485 module can easily be interfaced with microcontrollers for example Arduino as it uses 5V logic levels. Some key features of the RS485 Module include: Differential signalling for better noise immunity
