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 Pimoroni Pico Plus 2) or add-on using a handy cable (of course, there's also pads if you'd prefer to solder wires to it).
