Raspberry Pi Radio Module 2 (CYW43439)

Description

The Raspberry Pi Radio Module 2 is an optimized wireless solution built around Infineon Technologies’s CYW43439 chip, specifically tailored for Raspberry Pi’s budget-friendly microcontrollers like the Pico W and Pico 2 W. It provides robust 2.4GHz Wi-Fi 4 (802.11n) and Bluetooth 5.2 capabilities, making it an ideal choice for a wide range of low-cost, connected embedded projects.

This compact module features castellated edge pads, enabling flexible mounting options and streamlined hardware integration into custom PCBs. With an integrated 2.4GHz antenna, developers are freed from complex antenna design considerations. The inclusion of internal Power Amplifier (PA) and Low-Noise Amplifier (LNA) ensures reliable signal integrity and extended range.

Beyond its hardware simplicity, the Radio Module 2 boasts full modular certification, significantly reducing the burden of regulatory compliance for products incorporating this module. Its compatibility with Raspberry Pi Pico W and Pico 2 W SDKs, along with a minimal I/O gSPI host interface, ensures rapid development and deployment, accelerating time-to-market for wireless-enabled devices.
