1 Introduction The WU105 WiFi Module is a small form-factor, single stream, 802.11b/g/n WiFi module with on-board low power application processor. It is a low cost serial WiFi module, support UART-WiFi data transmission. The WU105 has been optimized for client applications in smart home, enterprise, smart grid, home automation and control that have lower data rates and transmit or receive data. The WU105 WiFi module also enable rapid application development of ultra low power devices with the complete application SW on-chip. The module utilizes the flexible low power single stream MT7681 WiFi (b/g/n) SOC. This combination makes the WU105 WiFi module an ideal solution for low power automation and sensor solutions because of its high efficiency and low power consumption (When in standby mode, current consumption is less than 10uA while still monitoring peripherals). Furthermore, due to the encryption and tamper detection capabilities of the module it is also suitable for security applications. The WU105 WiFi i Module can be used to design applications using 802.11b/g/n communication protocols. All features are enhanced by a built-in antenna, external antenna connector. This module has interface ports including power supply pins, GPIO ports and UART ports. Figure 1: Top View 第 2 页
