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 ) or add-on using a (of course, there's also pads if you'd prefer to solder wires to it). 

Host and SP/CE cable are not included.

Features

• Raspberry Pi RM2 module (), 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)

Pinout and Schematic

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. 

• Builds for Pico / RP2040 are coming soon!

You'll need to set the pins that the module is connected to before you do anything with the network. On a (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 or ) 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

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.
