ESP32 WiFi wireless data transmission/acquisition/control PCBA development board

 

WIFI RTU product overview

WiFi RTU is a collection and control terminal device that adopts WiFi wireless data transmission. The device adopts ESP32 module, supports more free development and more flexible scene application, supports TCP, UDP, network protocols, and provides users with fully transparent data transmission methods. Support custom heartbeat package, registration package, data guide package, support through Shanyun port, users do not need to set up servers, fully support industrial configuration applications, users do not need to care about complex network protocols, through transparent serial ports, wireless data can be sent and received, so that Access the Internet anytime, anywhere on your device.


WiFi RTU supports TCP and UDP two message formats, users can choose freely. 4 analog outputs, 4 switch outputs and 4 relay outputs are suitable for most application scenarios and can solve data transmission problems without any wiring. The WiFi RTU provides wireless data transmission and acquisition control anywhere a WiFi network is available.
