RMC20452T

RMC20452T is a Raspberry Pi Radio module 2. It 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. The 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.
