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 Features: Reliable Wireless Connectivity: 2.4 GHz Wi-Fi 4 (802.11b/g/n) Bluetooth 5.2 with support for both Classic and Low Energy (LE) Hardware Integration Made Simple Compact 1×1 SISO (Single Input, Single Output) design Shared single antenna for Wi-Fi and Bluetooth Castellated edge pads for flexible mounting options Robust Wireless Performance Integrated internal Power Amplifier (PA) and Low-Noise Amplifier (LNA) Supports 20 MHz channels with PHY data rates up to 96 Mbps Power Efficiency Low-power operation with optimized consumption modes: 1.19 mA (IEEE Power Save, DTIM1) 43 mA (active receive, MCS7 at –50 dBm) 271 mA (active transmit, MCS7 at 16 dBm) Software Compatibility : Fully compatible with Raspberry Pi Pico W and Pico 2 W SDKs Extended I/O Capabilities : Includes three host-controlled GPIOs for general-purpose use Streamlined Compliance : Region-specific modular wireless certification to ease regulatory approval Low-Pin-Count Interface : Uses a minimal I/O gSPI host interface for easier hardware integration Package Includes: 1 x Raspberry Pi Radio Module 2
