1. Product Overview
1.1. Introduction
BroadLink WT1HB12 is the industrial leading 2.4Ghz 802.11 b/g/n embedded Wi-Fi module
which delivers unmatched performance and codeless development in a compact package,
providing a quick, easy and cost effective way for developers and manufacturers to add Wi-
Fi connectivity for home automation, lighting control, energy efficiency and other IOT
applications.
WT1HBS12 combines a 2.4Ghz 802.11 b/g/n radio transceiver with MAC, baseband
processing and optimized Wi-Fi protocols, configuration profile and network stack It
supports UART communication with other devices and can be widely used in applications
like smart home, remote monitoring and medical care. It is an ideal solution for developers
and manufacturers with limited RF and embedded programming expertise as it significantly
reduces RF design time and removes the burden of testing and certification.
WT1HBS12 integrates a 32-bit RISC processor and an 8 Mbit flash which is capable for most
of control-type IoT application.
