Isisekelo Ukusajingijolo Pi iyaqhubeka emizamweni yayo yokwenza kancane ibhodi lentuthuko elidume kakhulu emakethe, nokuthi, ngokukhishwa kwayo okusha, bakwazile ukunciphisa ibhodi libe lincane ngombono wokunikeza into encane kakhulu futhi eshibhile kakhulu Ngisikhathi esifanayo. kanjalo ne Okusajingijolo Pi Pico.
indlu brand ubuchopho
Enye yezinto ezintsha ezimangalisa kakhulu zalesi silawuli esincane ukuthi sifaka iphrosesa ye-RP2040, i-chip eklanywe yi-Raspberry Pi Foundation ngokwayo, into esimema ukuthi sicabange ukuthi sizobona ama-chips azayo kamuva. Lokhu mhlawumbe kukuvumele ukuthi udizayine isilawuli esicaciswe kakhudlwana nesihleleke kahle kuyo yonke eminye imisebenzi, ukuze ukusebenza kwaso kuthakazelise kakhulu.
Le chip eyinhloko isekelwe ku-dual-core ARM Cortex M0+ esebenza ngo-133 MHz, eno-254 KB we-RAM kanye nembobo ye-USB encane lapho kutholwa khona amandla.
Izici ze-Raspberry Pico
- I-RP2040 microcontroller yakhelwe i-Raspberry Pi
- Isekelwe ku-0 Mhz dual-core ARM Cortex M133+
- 264 KB SRAM
- 2MB inkumbulo ye-Flash engaphakathi
- I-USB 1.1 enokwesekwa komsingathi
- Imodi yamandla aphansi kanye ne-hibernation
- Hudula bese uwisa izinhlelo usebenzisa isitoreji esiningi se-USB
- 26 pin multifunction GPIO
- 2 SPI, 2 I2C, 2 UART, 3 12-bit ADCs, 16 iziteshi ze-PWM
- Ithempelesha inzwa
- Iwashi elisebhodini elinembile
- Imitapo yolwazi yendawo entantayo eku-chip
- 8 izimbobo ze-I/O (PIO) ezihlelekayo
Ipuleti eliphelele lazo zonke izinhlobo zabasebenzisi
Njengoba ubona ezithombeni, ibhodi linenani lamaphinikhodi angu-26 we-GPIO kanye nokokufaka okuthathu kwe-analog ukuze abasebenzisi bakwazi ukuletha amaphrojekthi abo ekuphileni ngokukhululekile. Ukuyivula, kuzodingeka sixhume kuphela isixhumi se-USB encane bese ucindezela inkinobho yamandla ukuze okokusebenza kusibone ngokushesha.
Ngenxa yokuguquguquka kwalo, leli bhodi liyimodeli efanelekile yalabo basebenzisi abaqalayo emhlabeni wezinhlelo futhi nakulabo abathuthuke kakhulu asebevele benemibono engqondweni mayelana ne-IoT noma amaphrojekthi ezishintshayo asekhaya.

Kuze kube manje, i-Raspberry isebenze nezinkampani ezifana ne-Adafruit ne-Arduino, phakathi kwabanye, ukuletha izesekeli ekuphileni ezisebenza njengama-plugin ukudala kalula amadivayisi. Phakathi kwezinketho eziningi, i-Pimoroni inikeza ikhonsoli ene-Raspberry Pi Pico ehlanganisiwe ye-£ 58,50.
👀 kube @Raspberry_Pi I-RP2040-powered encane ephathwa ngesandla esuka @pimoroni?!

Ibiza malini i-Raspberry Pi Pico futhi ungayithenga kuphi?
Kodwa uma kukhona okungangabazeki okuzohlonza le modeli ye-Raspberry Pi, iyinani layo. Le nkampani imemezele ukuthi intengo esemthethweni yalo modeli izoba ngamadola angu-4, emakethe yaseYurophu izohumusha phakathi kwe-4 ne-5 euros. Kuyinani elimangalisayo ongakwazi ngalo ukuletha amaphrojekthi athakazelisa kakhulu ekuphileni, ngakho umkhawulo uzomane ube emcabangweni womklami ngamunye. Phakathi kwabasabalalisi kukhona
Siyaqiniseka ukuthi amaphrojekthi athakazelisa ngokukhethekile azovela ezinyangeni ezizayo asebenzisa usayizi omncane waleli bhodi, ngakho-ke sizobona ukuthi ayasimangaza ngekhonsoli ephathekayo noma enye indalo efanayo.
