Description
Overview
GAOTek Serial Port Wireless Wifi Module is an embedded serial port to Ethernet module based on series launched .Integrating an optimized TCP/IP protocol stack, it makes it easy for users to accomplish the network access of embedded devices and greatly reduces the development time cost. Moreover, the module is designed to be compatible with half pads and through-hole connectors. As the board width of it is the generic width, the module can be directly welded to boards, or connectors, or even breadboards, which is convenient for users to apply in different scenes. The series IC is the SOC integrated with 2.4 GHz Wi-Fi and BT dual modes，with ultra-high RF performance, stability, versatility, reliability, and ultra-low power consumption.
Features
- Support wired network access
- Support user secondary development
