Aikin Raspberry Pi ya gabatar da sabon hukumar Rasberi Pi Pico W, wanda ke ci gaba da haɓaka ƙaramin hukumar Pico, sanye take da na'urar sarrafa kayan masarufi ta RP2040. An bambanta sabon bugu ta hanyar haɗin haɗin Wi-Fi (2.4GHz 802.11n), wanda aka aiwatar akan tushen Infineon CYW43439 guntu. Hakanan guntu na CYW43439 yana goyan bayan Classic na Bluetooth da Ƙarfin Ƙarfin Ƙarfin Bluetooth, amma har yanzu ba a haɗa su cikin hukumar ba. Sabuwar hukumar ta ci $6, wanda ya fi dala biyu tsada fiye da zabin farko. Daga cikin bangarorin aikace-aikacen, ban da rabawa tare da kwamfutocin Raspberry Pi, haɓaka tsarin da aka haɗa da tsarin sarrafawa don na'urori daban-daban, zaɓin Wi-Fi yana sanya shi azaman dandamali don ƙirƙirar na'urorin Intanet na Abubuwa waɗanda ke hulɗa akan hanyar sadarwa.
Guntuwar RP2040 ta haɗa da mai sarrafa dual-core ARM Cortex-M0+ (133MHz) tare da 264 KB na ƙwaƙwalwar shiga bazuwar ciki (SRAM), mai sarrafa DMA, firikwensin zafin jiki, mai ƙidayar lokaci da mai sarrafa USB 1.1. Allon yana ƙunshe da 2 MB na ƙwaƙwalwar Flash, amma guntu yana goyan bayan faɗaɗa har zuwa 16 MB. Don I/O, akwai tashar jiragen ruwa na GPIO (filin 30, wanda 4 an ware su don shigarwar analog), UART, I2C, SPI, USB (abokin ciniki da mai masaukin baki tare da goyan bayan booting daga fayafai a tsarin UF2) da ƙwararrun 8 fil PIO (Injunan Jiha I/O masu shirye-shirye) don haɗa kayan aikin ku. Ana iya ba da wutar lantarki daga 1.8 zuwa 5.5 volts, yana ba da damar samun madafan iko iri-iri, gami da baturan AA biyu ko uku na yau da kullun ko daidaitattun batura lithium-ion.
Don ƙirƙirar aikace-aikace, ana iya amfani da C, C++ ko MicroPython. An shirya tashar tashar MicroPython don Rasberi Pi Pico tare da marubucin aikin kuma yana goyan bayan duk damar guntu, gami da nata hanyar sadarwa don haɗa kari na PIO. An daidaita yanayin tsara shirye-shirye na Thonny don haɓakawa don guntu RP2040 ta amfani da MicroPython. Ƙarfin guntu ya isa don gudanar da aikace-aikace don magance matsalolin ilmantarwa na inji, don haɓakawa wanda aka shirya tashar tashar tashar TensorFlow Lite. Don samun damar hanyar sadarwa, an ba da shawarar yin amfani da tarin hanyar sadarwa ta lwIP, wanda aka haɗa a cikin sabon sigar Pico SDK don haɓaka aikace-aikace a cikin yaren C, da kuma a cikin sabon firmware tare da MicroPython.
