The Raspberry Pi Radio Module 2 is a fully certified, compact wireless module designed for seamless integration into OEM products or custom PCBs. Built for Raspberry Pi microcontrollers like the Pico W and Pico 2 W, this module enables reliable 2.4GHz Wi-Fi 4 and Bluetooth 5.2 connectivity with minimal I/O overheadperfect for IoT, smart devices, and low-power applications.

Powered by Infineons CYW43439 chip, the RM2 combines Wi-Fi and Bluetooth in a small 16.5mm 14.5mm castellated-edge package, supporting both Bluetooth Classic and Low Energy (LE). With its integrated antenna and low component count, its ideal for cost-sensitive mass production and space-constrained designs.
