Raspberry Pi Radio Module 2:
Wireless Wi-Fi 4 & Bluetooth 5.2 in mini format
The Raspberry Pi Radio Module 2 is a compact, modular, certified radio module that combines Wi-Fi 4 (802.11n, 2.4 GHz) and Bluetooth 5.2 (Classic & LE) in a single component—ideal for cost-effective IoT, industrial, and B2B applications. With integrated PA, LNA, and a common 2.4 GHz PCB antenna, the module saves space and significantly simplifies hardware design.
The module uses the same Infineon CYW43439 radio chip as the Raspberry Pi Pico W and Pico 2 W, including full software compatibility with their SDK. Thanks to its compact form factor (approx. 16.5 × 14.5 mm) and the low-pin-count SPI (gSPI) interface, it is extremely efficient in integration—particularly suitable for use in industrial embedded systems or in series production, as additional components are virtually eliminated.
Full modular certification facilitates market launch, especially for manufacturers who want to avoid complex radio approvals. This radio module combines the following key advantages: Raspberry Pi Radio Module 2 enables fast, stable connections via Wi-Fi 4 and Bluetooth 5.2 , high feature density in a compact footprint, low production costs, and direct scalability for professional applications.
