Raspberry Pi just shocked the tech world with a tiny wireless gadget that costs almost nothing. The Radio Module 2 sells for only four dollars and packs serious wireless power into a space smaller than a postage stamp. Makers and developers can add Wi-Fi and Bluetooth to their projects without breaking the bank. The little device measures just 16.5 millimeters wide and works with popular Pico boards. Tech companies love how cheap it makes wireless features for their gadgets.
The module uses the same radio chip that powers other Raspberry Pi wireless boards. Infineon built the CYW43439 chip that handles both Wi-Fi 4 and Bluetooth 5.2 connections. Developers save huge amounts of time because the module already passed all the required wireless tests. Companies can skip expensive certification steps that usually slow down product launches. The built-in antenna means no extra parts to buy or install.
SparkFun and Pimoroni already started using these modules in their new products. The Thing Plus and Pico Plus 2 W boards show how well the module works in real devices. Small teams and big companies both want this affordable wireless solution for their projects. The module connects through a simple SPI interface that saves valuable pins on the main processor. Raspberry Pi created a wireless component that changes how people think about adding connectivity to electronic devices.
