EMW3080
1. Product Introduction
EMW3080 is a cost-effective embedded Wi-Fi module released by MXCHIP with high integrating ARM
CM4F, WLAN MAC/Baseband/RF. Maximum frequency 133MHz with 256KB SRAM and 2M FLASH. Power
supply is DC 3.3V. Installation modes are LGA SMT and Pin Connection. Peripheral: 2xUART / 1x SPI /2x I2C /
6x PWM / Up to 13 GPIOs.
EMW3080 operates MiCO 3.0 IoT operating system, supporting Micoder 1.0 development system. Provide
fast, stable and secure end-to-end cloud links to users with integrate TCP/IP protocol stack, various security
encryption algorithm, intelligent cloud such as MXCHIP easylink/Alink 1.1/Joinlink 3.0/Hilink/One
Net/Gome/Suning, oversea cloud such as AWS/Ayla/Azure/IBM Watson/Google/Apple Homekit.
EMW3080 (A): Provide securityencryption chip to the integrity and legality and cloud communication safety
of client firmware.
EMW3080 (B): Abundant peripherals and memory to supply most application and multi-cloud requirement.
