Models QCA4002 and QCA4004 Wi-Fi Modules

QCA400x is an intelligent Wi-Fi platform for the Internet of Things (IoT). This complete networking platform enables customers to add full-featured Wi-Fi to a wide variety of products with minimal development effort and cost.

QCA400x is a single-stream (1x1) IEEE 802.11n single-band (QCA4002) or dual-band (QCA4004) System-on-Chip (SoC) or module solution for the Internet of Things (IoT). The highly integrated Wi-Fi link includes an energy efficient on-board power amplifer and LNA. For the 2.4GHz band, RF switches are also integrated. The QCA400x is optimized for low system cost, and minimizes the number of components required to achieve a reliable Wi-Fi link. In addition, the QCA4004 can operate in a pure hostless mode of operation.
The QCA400x platform provides two host interfaces for connecting to local system controllers. A UART-based host interface can be used for rapid development and deployment of simple data streams between the local device and the internet cloud. An SPI slave interface is available for applications that require more advanced connectivity to the network. It supports a network stack along with SSL security, enabling full-featured internet connectivity and reliable information exchange in a small, low cost system. It supports the AllJoyn™ connectivity software framework and services, allowing devices to discover, connect and communicate directly with one another.
