NS4 Serial port to Ethernet module
[Interface signal]：Ethernet
[Interface mode]：UART serial port
[Size]：27*27*2.8mm
[Working voltage]：3.0~5.5V
[Introduction]：NS4 is an Ethernet serial server module that realizes serial data ⇌ Ethernet data conversion; it has a variety of Modbus gateway modes and TCP/DUP/MQTT/HTTP IoT gateway modes, which can meet the networking functions of various serial devices/PLCs. The module adopts LCC package, which is convenient for user equipment to be integrated on the PCB board.
