1.1 Overview

The SimpleLink™ Wi-Fi™ CC33xx family of devices is where affordability meets reliability, enabling engineers to connect more applications with confidence. CC33xx devices are single-chip integrating both Wi-Fi 6 and Bluetooth Low Energy (BLE) 5.4. The following two devices from the CC33XX family are also pin to pin compatible:

  • CC3300: A 2.4GHz Wi-Fi 6 companion IC.
  • CC3301: A 2.4GHz Wi-Fi 6 and Bluetooth Low Energy 5.4 companion IC.

This guide walks through the hardware requirements and recommendations for integrating CC33xx devices.
