SMT Package

SMT Package

High-Performance module is launched by high-flying and it supports 802.11b/g/n protocol. Customers do not need to know complex TCP/UDP protocol to achieve devices connection mutually. With High-Performance module, the traditional devices or MCU controlled devices can easily access to the wireless network through UART or 100M Ethernet interface.
