Raspberry Pi PICO W brings Bluetooth and WiFi to the PICO

The shiny box is the wireless antenna

The Raspberry Pi PICO is an awesome device. Super cheap, super easy to program and super easy to connect to stuff. The only thing about it that I didn’t like about it was the lack of any wireless connectivity. That’s changed now, with the launch of the PICO W. This adds a Infineon CYW43439 wireless chip to the PICO which brings Bluetooth and WiFi connectivity. The new PICO W is physically compatible with the old one. The pins are pretty much the same, although three of them (ones you don’t use much) are now accessed slightly differently.

At the moment there are no drivers for Bluetooth and you can only use the WiFi from Micro Python programs (not C++ or Circuit Python). But I expect that to change pretty quickly once folks get to grip with the device.

There’s a really good description of the new PICO W plus sample code in this month’s MagPi magazine which you can find here.
