EMW3166 is one embedded Wi-Fi module of low-power, small-size and low-cost designed by MXCHIP. It integrates one Cortex-M4 microcontroller of 256Kbytes SRAM and 1Mbytes on-chip flash with another 2Mbytes on-board SPI flash added. Various peripheral interfaces of analog and digital are available. The power supply voltage is 3.3V. It applies half-hole footprint for hand-soldering. The module runs MICO, which is the IOT OS System of MXCHIP, and is available for secondary development. The TCP/IP protocols and security encryption algorithm could be applied in various Wi-Fi applications. In addition, several particular firmware prepares for some typical applications, like UART to Wi-Fi DTU, easylink configuration and services for cloud interfacing.
