Add 2.4GHz wireless and Bluetooth functionality to an existing project with this handy breakout featuring Raspberry Pi's RM2 module.
RM2 uses the same two-in-one wireless and Bluetooth module that's found on Raspberry Pi Pico W, making it easy to use directly with any RP2040 or RP2350 board.
This breakout has a SP/CE connector on board so you can connect it easily to any SP/CE compatible microcontroller (like Pico Plus 2 or Pico LiPo 2) or add-on using a handy cable (of course, there's also pads if you'd prefer to solder wires to it).

Pinout and Schematic
Getting Started
You can use RM2 Breakout with Raspberry Pi Pico 2 or other RP2350 based microcontrollers using our custom MicroPython build that allows for pin re-assignment.
You'll need to set the pins that the module is connected to before you do anything with the network. On a Pico Plus 2 (with a RM2 breakout connected via SP/CE cable), that would look like this:
wlan = network.WLAN(network.STA_IF, pin_on=32, pin_out=35, pin_in=35, pin_wake=35, pin_clock=34, pin_cs=33)
Alternatively, if you have a RP2040 or RP2350 board that exposes GP23, GP24, GP25, and GP29 (such as PGA2040 or PGA2350) you can wire the module up to the default Pico W pins and you won't need to do any pin configuration. The pins are:
- WL_ON -> GP23
- DAT -> GP24
- CS -> GP25
- CLK -> GP29
If you have a Pimoroni Pico LiPo 2 then the SP/CE pins are used by default for Wi-Fi, making things super easy.
Notes
- By default the BL_ON pin is wired to the WL_ON pin. There is a cuttable trace on the rear of the board, if your project needs these to be disconnected.
