Last January, Raspberry released its first Pi Pico W board on its own silicon. It became incredibly popular, but had one flaw in the context of working with Internet of Things (IoT) gadgets – the absence of any method of connecting to the Web. Raspberry recognized this shortcoming and released the Pi Pico W for $6. The Pico H ($5) and Pi Pico WH ($7) models also debuted with it, but it is the Pico W that is of most interest.
The Pi Pico W is still based on the RP2040 microcontroller, just like the regular Pi Pico. It is built on a 40nm process and includes 2x 133MHz Cortex-M0+ cores, 264KB of onboard SRAM, and a unique programmable I/O subsystem.
The main innovation was the CYW43439 wireless chip from Infineon (2.4 GHz, 802.11n) – like in other modern Raspberry products, it is enclosed in a metal case. This solution is convenient for integrating the board into other products. It is noteworthy that the chip itself also supports Bluetooth, both the regular protocol and Low Energy. However, it is not available on the Pico W right now, at the time of launch, but the developers do not exclude its appearance in the future.
