WiFi to UART module

Support RS-232,RS-422/485 Modbus TCP RTU,

Support Android & iOS

(Model: WM-SII)

Description

WM-SII is a complete IEEE 802.11 b/g/n WiFi module for embedded wireless solution. It is a cost effective and low power solution for M2M and IOT application. It is designed for smart grid, smart home, security, building automation, toys, robots, remote health and wellness monitoring and other M2M and IOT applications.

The module integrates an ARM Cortex-M3 MCU and Broadcom WiFi MAC/front end. It manages all the MAC and TCP/IP stack embedded. Except the on board PCB antenna, an external antenna connection pin is also provided to maximum the usage. When both antenna is existed, it will automatically diverse to select a better antenna.

Different level of wireless connection is supported. Direct connection could be a cable replacement in M2M scenario. Local networking could be an easy adoption for factory and building. We also provide cloud package to help customer to connect to Internet and manage through the internet. You just need to connect your system/device/asset to WM-SII through UART and then use provided web/APP interface to manage your connection. Thus, it can be used to enable wireless connectivity to the simplest existing products with minimal engineering effort.
