Pimoroni Pico Plus 2 W combines RP2350B MCU with Raspberry Pi RM2 Wi-Fi and Bluetooth module

Raspberry Pi released the Raspberry Pi Pico 2 a few months ago, featuring the new RP2350 chip. Despite several upgrades, it lacks wireless connectivity like Pico W. While there’s no official Raspberry Pi Pico 2 W yet, Pimoroni has developed an unofficial alternative, the Pimoroni Pico Plus 2 W, which integrates Wi-Fi and Bluetooth using a yet-to-be-formally-announced Raspberry Pi RM2 module and potentially set to appear in a future Pico 2W.

The Pimoroni Pico Plus 2W board is powered by the Raspberry Pi RP2350B dual-core Arm Cortex-M33 microcontroller, features 16MB of QSPI flash with XiP support, 8MB of PSRAM, wireless connectivity, a USB Type-C port for power and data, and a Qwiic/STEMMA QT connector for breakout board integration.

A few days ago, we covered the Pimoroni Explorer board, an electronic prototyping board built around the Raspberry Pi RP2350B chip. It features a 2.8-inch LCD screen, a speaker connector, and multiple I/O options, making it ideal for building circuits, prototyping projects, and even creating small robots. We’ve also written about the RP2350 Stamp XL, Jumperless V5 programmable breadboard, and Bus Pirate 6. Feel free to check those out if you’re interested in these products.

The highlight of the Pimoroni Pico Plus 2 W is the Raspberry Pi RM2 module, which resembles an ESP32 package but houses the same Infineon CYW43439 chip used in the Raspberry Pi Pico W. This allows for easy online connectivity with just a few lines of MicroPython, and it also supports Bluetooth. Like other RP2350 boards, it supports MicroPython, CircuitPython, C, and C++. You can visit their GitHub repository for more information about the breakout board and supported C++/MicroPython builds.

The Pimoroni Pico Plus 2 W is available for $18.48 at Pimoroni’s official store. The company also offers various accessories for the Pimoroni Pico, including headers, a USB-A to USB-C cable, the Pico Omnibus, and 3-pin, 4-pin, and 8-pin JST-SH cables.
