QCA4020

1 Introduction

This is a miniPCIe card that supports multi-mode intelligent connectivity. It supports dual-band WiFi,

Bluetooth 5, and ZigBee. It is based on Qualcomm QCA4020 System-On-Chip (SoC). It has low power

SoC that integrates a Cortex M4F for application processing, Cortex M0 for network stack

processing, and a separate processor for Wi-Fi stack designed to enable a highly concurrent

multiple radio solution.

The QCA4020 SDK pre-integrates support for advanced security features and multiple software

and cloud ecosystems.

Designed to address IoT fragmentation and support for interoperability, this solution is ideal for

multiple IoT industries from home control and automation, networking, home entertainment

and smart cities.
