W ith a surprise June 2022 release, we see a new Raspberry Pi Pico W – correcting one of the original’s omissions – this $6 microcontroller looks much like its predecessor, but under a tiny silver case lies a Wi-Fi chip that takes the Pico into the world of IoT. It may not be the first RP2040 board to offer Wi-Fi – but we’re sure that the Raspberry Pi Pico W is going to go straight on to our list of best RP2040 boards.
There isn’t really much difference between the original Pi Pico and the new Pico W. There’s the same GPIO, microUSB port, dimensions and SoC. The only difference is the inclusion of Infineon’s CYW43439 2.4GHz Wi-Fi chip. Looking at Infineon’s datasheet for this chip,
