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 overhead—perfect for IoT, smart devices, and low-power applications. Powered by Infineon’s 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, it’s ideal for cost-sensitive mass production and space-constrained designs. Key Features Wireless: 2.4GHz Wi-Fi 4 (802.11n) and Bluetooth 5.2 Bluetooth Range: Up to 100 m (Class 1) or 10 m (Class 2) Antenna: Integrated 2.4GHz antenna with Wi-Fi/Bluetooth coexistence Form Factor: Compact 16.5 × 14.5 mm castellated package Compliance: FCC modular conformance, certified for global use Interface: Low-pin-count qSPI host interface for simple integration GPIO: Three host-controlled GPIOs for extra I/O flexibility Compatibility: Fully compatible with the Raspberry Pi Pico W SDK Power Efficiency: IEEE Power Save (1.19 mA average) Receive active (43 mA @ −50 dBm) Transmit active (271 mA @ 16 dBm) Temperature Range: −30°C to +70°C Speed: Up to 96 Mbps (PHY rate) Designed For OEM developers and engineers integrating wireless into custom designs Projects requiring simple, certified Wi-Fi/Bluetooth connectivity Raspberry Pi-based products needing modular, scalable wireless interfaces Resources RM2 Product Brief RM2 Datasheet
