Projekt Raspberry Pi predstavil nov\u00fa dosku Raspberry Pi Pico W, ktor\u00e1 pokra\u010duje vo v\u00fdvoji miniat\u00farnej dosky Pico vybavenej mikrokontrol\u00e9rom RP2040, vyvinut\u00fdm vlastnou cestou. Nov\u00e1 verzia sa od prv\u00e9ho z\u00e1kladn\u00e9ho modelu odli\u0161uje integr\u00e1ciou podpory Wi-Fi (2.4GHz 802.11n), realizovanou na z\u00e1klade \u010dipu Infineon CYW43439. \u010cip CYW43439 tie\u017e podporuje Bluetooth Classic a Bluetooth Low-Energy, ale tieto funkcie zatia\u013e nie s\u00fa v doske akt\u00edvne. Cena novej dosky je 6 dol\u00e1rov, \u010do je o 2 dol\u00e1re viac ako u predch\u00e1dzaj\u00facej verzie.

\u010cip RP2040 obsahuje dvojjadrov\u00fd procesor ARM Cortex-M0+ (133 MHz) s 264 kB vstavanou opera\u010dnou pam\u00e4\u0165ou (SRAM), DMA ovl\u00e1da\u010dom, sn\u00edma\u010dom teploty, \u010dasova\u010dom a USB 1.1 ovl\u00e1da\u010dom.
