Eben Upton, Wanda ya kafa Raspberry Pi, kwanan nan ya sanar da sabon "Rasberi Pi Pico W" tare da ginanniyar Wi-Fi. Rasberi Pi Pico W shine ingantaccen sigar Rasberi Pi Pico na $4 na bara.
Ya kamata a lura cewa don haka ba za a iya amfani da ita azaman kwamfuta ba; a maimakon haka, yana aiki azaman kwamiti na microcontroller don ayyukan lantarki na DIY. Kamar ainihin Pi Pico, yana da microcontroller RP2040 tare da muryoyin ARM Cortex-M0+ guda biyu da 264kB na SRAM.
Ga waɗanda har yanzu ba su san Rasberi Pi ba, ya kamata su san cewa wannan shine nanocomputer na allo guda na tushen ARM Girman katin kiredit ɗin da malamai daga Sashen Kimiyyar Kwamfuta a Jami'ar Cambridge suka tsara a matsayin wani ɓangare na Rasberi Pi Foundation.
An ƙirƙiri shi ne don haɓaka aikin kwamfuta, damar yin amfani da kwamfutoci da ƙirƙirar dijital. Rasberi Pi yana goyan bayan aiwatar da bambance-bambancen GNU/Linux da yawa, musamman Debian, da software masu dacewa. Hakanan yana aiki da tsarin aiki na Microsoft Windows: Windows 10 IoT Core6, Windows 10 akan ARM, Google Android Pi7 har ma da nau'in OS/MVT na IBM tare da tsarin APL\3602.
"A watan Janairu na shekarar da ta gabata, mun ƙaddamar da $4 Rasberi Pi Pico, samfurin mu na farko na tushen silicon wanda aka tsara a nan Rasberi Pi. Zuciyarta ita ce microcontroller RP2040, wanda aka gina akan tsarin TSMC mai ƙarancin ƙarfi na 40nm tare da haɗa nau'ikan 133MHz Arm Cortex-M0+, 264KB na kan-chip SRAM, da tsarin mu na musamman na I/O, "in ji Eben Upton.
Game da Rasberi Pi Pico W
Gidauniyar Raspberry Pi ta saki sabbin mambobi uku na dangin Pico. Rasberi Pi Pico W ($ 6) yana kawo hanyar sadarwar mara waya ta 802.11n zuwa dandalin Pico, yayin da yake kiyaye cikakkiyar jituwa tare da babban ɗan'uwansa. Pico H ($ 5) da Pico WH ($ 7) suna ƙara masu rubutun da aka riga aka ɗora da su da sabon mai haɗin kuskure na 3-pin zuwa Pico da Pico W bi da bi. Pico H da Pico W suna samuwa a yau; Kololuwar WH zai biyo baya a watan Agusta.
Babban haɓakawa tare da Pico W shine hadedde 2,4 GHz Wi-Fi module, wanda shine ƙari mai amfani ga duk wanda ke ƙoƙarin gina na'urorin gida mai wayo ko wasu irin waɗannan ayyukan. ace.
Tun lokacin da aka ƙaddamar da shi, an sayar da katunan Pico kusan miliyan biyu kuma RP2040 ya sami hanyar shiga cikin yawancin samfurori na ɓangare na uku. RP2040 yana da kyau don aikace-aikacen kasuwanci da masana'antu, kuma ƙarancin na'urori masu auna sigina na duniya ya ƙara haɓaka karɓuwa.
Tare da babban ƙwaƙwalwar ajiya da sassauƙa mai sauƙi, RP2040 ya dace da aikace-aikacen Intanet na Abubuwa (IoT). Koyaya, Pico kanta yana da fasalin da ya ɓace a bayyane ga IoT: hanyar haɗi zuwa cibiyar sadarwar, amma an yi la'akari da wannan yanayin kuma ƙungiyar a Rasberi yayi aiki tare da Infineon don ƙara guntu mara waya ta CYW43439 zuwa Pico W.
