方案介绍

QFN-1

为客户提供一个简单,易用,免费(第三方软件授权除外)和持续升级服务的物联网嵌入式开发平台。

QFN-1的目标是:偏向于高端物联网的应用设计,

核心器件:

NXP双核Sensor hub, LPC5410X,

Qualcomm低功耗WIFI芯片QCA4002,

同时嵌入了Apple的 MFI加密芯片。

其中

LPC54102具有100MHz M0+和100MHz M4F,

M0+专注于传感器接入和数据采集,

M4F负责系统任务处理和传感器本地算法支持,

嵌入无线驱动,云端驱动,

双向语音识别引擎,

加解密数据算法和用户私有协议等等;

如果需要OS支持的设备,只要把LPC54102通过SPI接入OS主芯片就可以了,

这样的最大好处就是简化了平台升级的难度。

QCA4004 Wi-Fi Modules

QCA400x is an intelligent Wi-Fi platformfor the Internet of Things (IoT). Thiscomplete networking platform enablescustomers to add full-featured Wi-Fi toa wide variety of products with minimaldevelopment effort and cost.

QCA400x is a single-stream (1x1) IEEE 802.11nsingle-band (QCA4002) or dual-band (QCA4004)System-on-Chip (SoC) or module solution for theInternet of Things (IoT). The highly integrated Wi-Filink includes an energy efficient on-board poweramplifier and LNA. For the 2.4GHz band, RF switchesare also integrated. The QCA400x is optimizedfor low system cost, and minimizes the number ofcomponents required to achieve a reliable Wi-Filink. In addition, the QCA4004 can operate in a purehostless mode of operation.

The QCA400x platform provides two host interfacesfor connecting to local system controllers. AUART-based host interface can be used for rapiddevelopment and deployment of simple data streamsbetween the local device and the internet cloud.An SPI slave interface is available for applicationsthat require more advanced connectivity to thenetwork. It supports a network stack along with SSLsecurity, enabling full-featured internet connectivityand reliable information exchange in a small, lowcostsystem. It supports the AllJoyn™ connectivitysoftware framework and services, allowing devicesto discover, connect and communicate directly withone another.
