Overview
Raspberry Pi Radio Module 2 is a cost-effective wireless module designed specifically
for use with Raspberry Pi’s low-cost, high-performance RP2040 and RP2350-series
microcontrollers, providing a natural path to scale for customers who have prototyped
with Raspberry Pi Pico products.
Radio Module 2 packages the same Infineon CYW43439 radio used on Raspberry Pi Pico
W and Pico 2 W, featuring 1×1 single-band 2.4GHz Wi-Fi® 4 (802.11n) and Bluetooth® 5.2,
with support for both Bluetooth Classic and Bluetooth Low Energy. Its integrated internal
PA, LNA, and T/R switch deliver excellent wireless performance even when sharing a
single antenna between Wi-Fi and Bluetooth.
Castellated edge pads and an on-board 2.4GHz antenna simplify design and assembly,
while a low-pin-count SPI host interface makes efficient use of the host CPU’s I/O budget.
A compact 16.5mm × 14.5mm form factor and minimal external component requirements
drive down production costs.
Radio Module 2 benefits from full modular certification, making it an ideal choice for
designers who wish to ship connected products without navigating the complex and
expensive radio certification process.
