Xa sithetha ngeRaspberry Pi, kulula ukucinga ukuba sibhekisa kwibhodi yophuhliso "enkulu", leyo sonke okanye uninzi lwethu oluyaziyo. Kodwa iRaspberry Pi Foundation isandula kukhupha isiphakamiso sesibini esibizwa ngokuba I-Raspberry Pi Pico leyo ngokwemilinganiselo inomdla ngakumbi kusetyenziso oluthile. Kakhulu ngakumbi ukuba uhamba nayo kunye nezinye ze eyona nto inomdla kunye nezixhobo zokuzonwabisa esele ikhona.
Yintoni iRaspberry Pico
I-Raspberry Pi Pico, ukuba awukayazi, yibhodi yophuhliso ehlangeneyo kakhulu. Yathiwa thaca ekuqaleni kuka-2021 ngenjongo yokubonelela ngokhetho olunye kwabo bafuna ukwenza iiprojekthi apho kufuneka izinto ezincinci.
Ngokwengqiqo, into yokuba ibhodi ehlangeneyo ngakumbi ithetha ukuzincama, njengamacandelo athile kunye noqhagamshelo olungathelekiswanga neRaspberry Pi 4. Nangona kunjalo, i iimpawu zobugcisa le Raspberry Pi Pico azimbi kwaphela.

Ukuthathela ingqalelo oko iRaspberry Pi Pico ixabisa nje i-euro ezi-5, Inyaniso kukuba akubi kwaphela kwaye kunokunika umdlalo omningi ukuba sele unamava okanye unezakhono ezaneleyo kunye nomnqweno wokulandela iiprojekthi ezininzi esele ziqala ukujikeleza kwi-intanethi.
Izincedisi ezilungileyo zeRaspberry Pi Pico
I-Raspberry Pi Pico yibhodi yophuhliso onokuthi wenze ngayo izinto ezininzi. Ukuqala, enkosi kwi-26 GPIO izikhonkwane kunye negalelo le-analog emithathu ingasetyenziselwa iiprojekthi ze-IoT (I-Intanethi Yezinto), i-automation yasekhaya okanye nokwenza izixhobo ezincinci zokudlala.
Kuyinyani ukuba kwezinye iintlobo zokusetyenziswa ayisiyiyo eyona ifanelekileyo, kuba leyo yenye inguqulelo yayo ephezulu kunye nonxibelelwano olungaphezulu (umfundi wekhadi le-microSD, ukuphuma kweHDMI, i-USB, njl.), kodwa ukuba uhamba nayo kunye neemodyuli ezithile ezinomdla. Uya kubona ukuba izinto ziyatshintsha.
I-PicoSystem
Oku ngaphandle kwamathandabuzo lolona ncedo lufanelekileyo kwaye yenye yeemodyuli ezilungileyo kakhulu esiya kuzibona ngexesha elide kwiRaspberry Pi Pico. Ngaphezu koko, phantse ngokuqinisekileyo ufuna enye ngokukhawuleza ukuba uyazi ngayo.
I-PicoSystem yinto yonke-kwinye oko kubandakanya isikrini, i-crosshead yolawulo kunye namaqhosha amane onokuthi ngawo ujike i-Raspberry Pi Pico ibe yi-console yepokotho encinci. Ukonwabela umdlalo wamaxesha ngamaxesha xa unemizuzu embalwa yokuphumla.
Incopho uMsongo
Le modyuli encinci enemilinganiselo efanayo njengoko iRaspberry Pi Pico inika inani elipheleleyo Ii-LED ezimhlophe ezili-119 zilungelelaniswe kwi-17 x 7 matrix. Ezi zinokulawulwa ngabanye kunye namaqhosha okuchukumisa amane avumela ukuba acwangciswe ngaphambili ukwenza iintshukumo ezahlukeneyo, ezinje ngokuzivula nokucima okanye iindlela zokukhanyisa ezahlukeneyo ezilandela iipatheni ezazisekwe ngaphambili.
I-Unicorn Peak
Ngendlela efanayo naleyo yangaphambili, le modyuli I-Unicorn Peak ihluke kwezinye ukuba endaweni yee-LED ezimhlophe zikhona Ii-RGB ze-LED. Ngokuqinisekileyo, oku kunika umdlalo omncinci kwaye ikuvumela ukuba wenze iiprojekthi okanye uzisebenzise ukubonisa iintlobo ezahlukeneyo zezilumkiso ngekhowudi yombala enokuthi iphunyezwe.
Ukuphumla, ziyafana ngokwasemzimbeni kumbandela wobungakanani kwaye ikwabonelela ngamaqhosha amane okucofa anokuthi aqwalaselwe ngokweemfuno zomsebenzisi kunye nemisebenzi afuna ukuyinika.
Incopho yomsindo
Le enye imodyuli eyenzelwe iRaspberry Pi Pico ikuvumela ukuba wenze iamplifier yomsindo ephucula amava esandi xa usebenzisa ii-headphones kunye nesixhobo sakho, nokuba yintoni na, ukuba ugqithise umqondiso wokuphuma kuyo ngaphambili. Oku kubulela a I-DAC edibeneyo leyo, njengabanye kwimarike, inceda ukugcwalisa izikhewu ezidityanisiweyo, ikakhulu, abanye abadlali ephathekayo.
Peak RGB Keypad
Nge I-4 x 4 iqhosha lematrix elikhanyayo nge-RGB LEDs Lo mnqongo ubonelela ngebhodi yezitshixo enokuthi iqwalaselwe njengoko umsebenzisi efuna, umzekelo, enze njenge lawula i-usb yesiko yokwazisa iintshukumo ezinkulu ezifumanekayo kwizicelo ezininzi ezinjengokusasaza okanye imidlalo.
umboniso wencopho
Umboniso wePico ngu 1,14 ″ IPS LCD isikrini enika isisombululo se Iiphikseli ezingama-240 × 135. Incinci, yinyani, kodwa inombala kwaye ikhatshwa ngamaqhosha amane kunye ne-RGB LED enokunika umdlalo omninzi. Ukuba ufuna umboniso omncinci ukubonisa ulwazi, lukhetho olufanelekileyo.
Umzekelo, khawufane ucinge ukuyisebenzisa ukwenza uhlobo oluthile lwesilawuli esizisebenzelayo sasekhaya onokuthi ngaso unxibelelane nezinye izixhobo ekhaya kwaye imeko yayo iboniswe esikrinini. Ngokuqinisekileyo ubona uninzi lokusetyenziswa kwayo ukuba sele unamava kule projekthi ngeRaspberry Pi.
Ukuqalisa ngeRaspberry Pi Pico
Zonke ezi modyuli ezinomdla zezo Pimoroni kwaye njengoko ubona, bavelisa iingcamango ezininzi. Kodwa ukuba into oyibuzayo ungaqala njani ukwenza iiprojekthi ezahlukeneyo ngeRaspberry Pi Pico, kungcono ukuyenza kunye ne Amaxwebhu asemthethweni anikezelwe yiRaspberry Pi Foundation. Oko kuya kukunceda ukuba wazi i-hardware, ukudibanisa kwayo kwaye ubone imizekelo yokuqala ukwazi amandla ayo kunye nokwenzeka.
Ukusuka apho, ngumba wokuqalisa ukuphanda nokungena iiforam ezikhethekileyo apho inkitha yabasebenzisi ichaza into abayenzayo, banike iingcebiso kunye nokunye okuninzi ukufumana okuninzi kwesi sixhobo.
