# EMC3290 AT Module

#1. Introduction

The EMC3080 series standard AT Combo module is an integrated hardware and firmware product launched by MXCHIP, used to quickly achieve product Wi-Fi communication functions. It is equipped with standard AT firmware and achieves high-speed connectivity through a "development free" and "zero code" approach. It greatly shortens the development and launch cycles of customers' complete machine products.

EMC3290-D is a Combo module of Wi Fi+BLE, with a working voltage of 3.3V and a working temperature of -40~85 ° C. The high-performance core is a 32 bit core with a main frequency of up to 200MHz, based on the latest ARM v8-M architecture. It not only has low power consumption, but also can perform floating-point operations and DSP instruction processing, thus efficiently completing audio encoding and decoding algorithms and deep learning model matching. Supports 2.4/5GHz dual band Wi Fi, ensuring stable internet connectivity at all times. BLE 5.0 technology not only facilitates users to quickly configure products, but also enables intelligent networking of a large number of local devices through Mesh technology for local remote control. The module is powered by a 3.3V single power supply and supports stamp hole installation, suitable for various smart home appliance application scenarios.
