HF-LPB300 Wi-Fi Module User Manual

HF-LPB300 Low Power Wi-Fi Module

The HF-LPB300 is a fully self-contained small form-factor, single stream, 802.11b/g/n Wi-Fi module, which provide a wireless interface to any equipment with a Serial/SPI/USB/GPIO interface for data transfer.HF-LPB300 integrate MAC, baseband processor, RF transceiver with power amplifier in hardware and all Wi-Fi protocol and configuration functionality and networking stack, in embedded firmware to make a fully self-contained 802.11b/g/n Wi-Fi solution for a variety of applications.

HF-LPB300 support AP+STA wireless networking and support Wi-Fi Direct mode. HF-LPB300 also provides wireless and remote firmware upgrade, which satisfied all kinds of application requirement. HF-LPB300 support wakeup-on-wireless feature which make it a very suitable solution for battery applications with excellent power save scheme.

The HF-LPB300 employs the world's lowest power consumption embedded architecture. It has been optimized for all kinds of client applications in the home automation, smart grid, handheld device, personal medical application and industrial control that have lower data rates, and transmit or receive data on an infrequent basis.

The HF-LPB300 integrates all Wi-Fi functionality into a low-profile, 23.1x32.8x 2.7mm SMT module package that can be easily mounted on main PCB with application-specific circuits. Also, module provides built-in antenna, external antenna option.
