1. Product summary
EMW3081 is a low-power and high performance embedded Wi-Fi module, which highly
integrates ARM-Cortex M3, WLAN MAC/baseband/RF, and built-in 512KB SRAM and 2MB SDRAM,
EMW3162 is 3.3V single-power supplysupports stamp hole SMT or DIPand supports serial
transmission and development two timesperipheral 1x HS UART / 1x SPI /1x I2C / 4x PWM / Up to
15 GPIOs.
EMW3081 runs the MiCO iot operating system and supports two times development
of Configuration, The user can use the MiCO TCP/IP protocol stack, multiple security encryption
algorithm to achieve a variety of embedded Wi-Fi applicationWe also provide a series of
independent firmware to meet different application scenariosSuch as UART-Wi-Fi transparent
transmission, EasyLink configuration, access a variety of cloud services。
