The Raspberry Pi Radio Module 2 (RM2) is a compact, self-contained wireless module developed to bring Wi-Fi and Bluetooth connectivity to Raspberry Pi microcontroller-based products. It is particularly suitable for embedded and production designs that require wireless connectivity without using a complete Pico W or Pico 2 W board. RP-008943-DS-7-Radio Module 2 D…
At its core is the Infineon CYW43439 wireless radio, providing 2.4GHz Wi-Fi 4 (802.11b/g/n) together with Bluetooth 5.2, including Bluetooth Classic and Bluetooth Low Energy. The module incorporates an internal PA/LNA and Raspberry Pi-designed PCB antenna, reducing the number of external RF components required in the host design. RP-008943-DS-7-Radio Module 2 D…
RM2 communicates with a Raspberry Pi microcontroller using a gSPI interface implemented through the microcontroller's Programmable I/O (PIO) system. The module also exposes three additional GPIOs that can be controlled by the host. Software support is provided through the Raspberry Pi Pico SDK and follows the same wireless software architecture used by Pico W and Pico 2 W.
