Raspberry Pi Radio Module 2

Raspberry Pi Radio Module 2 is a compact, affordable wireless module built specifically for Raspberry Pi’s powerful yet budget-friendly microcontrollers. At its heart is Infineon’s CYW43439 chip, which provides reliable 2.4GHz Wi-Fi 4 (802.11n) and Bluetooth 5.2 connectivity—ideal for low-cost, wireless projects.

Raspberry Pi Radio Module is designed to keep things simple and cost-effective, the module comes in a small form factor with minimal external components. It features castellated edge pads for flexible mounting options and includes a built-in 2.4GHz antenna, so there’s no need to worry about antenna design.

With full modular certification, integrating the Radio Module 2 into your product is easier, helping you meet regulatory requirements faster and with less hassle
