KB3077 wifi Module
- Detail
1. KB3077 Wifi module introduction
KB3077 is a new embedded UART-WiFi (serial port-wireless network) module introduced by Kingbot Technology. Built-in TCP / IP protocol stack, can realize the conversion between user serial port and wireless network (WiFi) interface.
Users can use the mobile phone or PC to communicate with the local area network through the KB3077 module, or connect it to a nearby WiFi router for remote communication between the mobile phone PC and the Internet, providing complete data transmission for the user's serial device through the network. Quick solution.
Main Features：
- Both support AP and Station mode, support AP and Station coexistence pattern;
- Coexist of LAN and Internet Data communication;
- Based both on Server and Client in the side of network;
- PC and Android APP setting tools;
- Support LAN and Internet setting, Support Serial and WiFi wireless setting;
- IP address and Device ID can be acquired through broadcast search instructions in LAN;
- TTL/RS232/RS485 interface options;
- Equip with internet communication platform (cloud data server).
