RM2 Wireless & Bluetooth Breakout (SP/CE)

Add 2.4GHz wireless and Bluetooth functionality to an existing project with this handy breakout featuring Raspberry Pi's RM2 module.

The 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 an SP/CE connector on board so you can connect it easily to any SP/CE compatible microcontroller (like Pimoroni Pico Plus 2) or add-on using a handy cable (of course, there are also pads if you'd prefer to solder wires to it).

The Host and SP/CE cables are NOT included but click here to see the cables we have in the store.

Note: 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.

Features

• Raspberry Pi RM2 module (CYW43439), supporting IEEE 802.11 b/g/n wireless LAN, and Bluetooth
• SP/CE connector (8-pin JST-SH)
• 0.1" headers (breadboard compatible)
• Compatible with Raspberry Pi Pico / Pico 2 / RP2040 / RP2350
• Input voltage: 3.0 - 3.3V
• Dimensions: 23.8 x 20.4 x 4.7 mm (L x W x H)

Getting Started

You can use RM2 Breakout with Raspberry Pi Pico (or other RP2040 or RP2350-based microcontrollers) using our custom MicroPython build that allows for pin re-assignment. 

• Download pirate brand MicroPython for RP2350 boards (with experimental wireless support)
• Builds for Pico / RP2040 are coming soon!
• MicroPython example

You'll need to set the pins that the module is connected to before you do anything with the network. On a Pimoroni Pico Plus 2 (with an 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 an 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
