It is an embedded, low-cost, small form, low-power Wi-Fi module. Also, the module features a 128Kilo Bytes of RAM, a Cortex-M4 core microcontroller, and a 512KB of chip flash. Furthermore, the module has 2M Bytes of SPI flash/onboard flash. 

Besides, the module is rich in various digital and analog peripheral resources and operates as a MiCO platform. Therefore, it allows users to create custom embedded Wi-Fi applications on a MiCO library. It is handy in managing TCP/IP stack processing and  Wi-Fi MAC. 

In addition, it has a self-hosted WiFi network library. Finally, the WiFi module sports an independent series of firmware such as Cloud services and Wireless UART. 

Module Specifications

The module measures 32mm by 16mm and has the following properties: 

• It requires 3v to 6v operating voltage and features 22 GPIO module pins 
• Secondly, it has a JTAG and SWD interface and 0.9 mm pitch pins

Wi-Fi Module

• It supports various protocols, including 802.11 n, 802.11 g, and 802.11 b. 
• Also, the module allows Enterprise, WPA/WPA2 PSK, WEP encryptions, and its receiver to have a sensitivity of -87 dBm. 
• Further, it enables EasyLink support and thus will connect to a wi-fi network in a single click.
• Lastly, the EMW3162 Wi-Fi module sports an external antenna with an IPEX connector and a Built-in PCB.

STM32F411CE microcontroller

• The STM Cortex-M4 operates at a frequency of 100 MHz and has a 128 KBs of RAM.
• Secondly, it has 2M external flash memory, which operates on an SPI bus

The Main Difference Between EMW3162 and EMW3165
