RaspRover Open-source 4WD AI Robot for Raspberry Pi
This is an RS232/485 device data acquisitor / IoT gateway designed for industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, serial port to HTTPD Client, etc. With RS232, RS485, WIFI and Ethernet interfaces, the module can realize functions such as serial port to WIFI, serial port to Ethernet, Ethernet to WIFI and so on. Onboard multiple power supply interfaces, supports 6~36V wide range power supply, and PoE function optional. Industrial grade metal case design, supports wall-mount and rail-mount installations, small in size, easy to install. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring...
