Muna da sabon hukumar SBC da ke ƙoƙarin yin koyi da Rasberi Pi Zero. Labari ne game da Waveshare RP2040-PiZero, amma wannan ya haɗa da microcontroller na RP2040 maimakon cikakken SoC mai iya tafiyar da Linux, kamar yadda yake tare da hukumar Raspberry Pi Foundation.
Ga sauran, za ku sami a Tsari iri ɗaya zuwa ainihin Pi Zero, tare da tashoshin jiragen ruwa iri ɗaya, kamar 2x USB-C, mini HDMI/DVI mai haɗawa don haɗa nuni na waje, katin ƙwaƙwalwar ajiyar microSD don ajiya, da kuma GPIO mai 40-pin don ayyukan DIY. Har ila yau yana da haɗin haɗin 2-pin don batir LiPo da da'irar caji.
Waveshare RP2040-PiZero: menene yake bayarwa?
Waveshare ya ƙara zuwa tallafin RP2040-PiZero don MicroPython, Arduino, da C da C++ harsunan shirye-shiryen SDK, wanda ya sa ya zama mai ban sha'awa ga ɗimbin ayyukan da za ku iya tunanin. Bugu da ƙari, za ku iya amfani da ayyukan PicoDVI da PIO-USB na yanzu. An yi bayanin komai da kyau kuma tare da misalai na lamba da zane-zane a cikin tsarin PDF waɗanda za ku samu akan wiki na hukuma.
Wataƙila PIO-USB da microHDMI tashar jiragen ruwa suna ɗaya daga cikin abubuwan da aka fi sani game da wannan jirgi, tunda akwai kuma wasu nau'ikan clones masu kama da ainihin Pi Zero, amma hakan ya rasa su. Har ila yau, idan kun damu da farashin, ya kamata ku san cewa za ku iya saya Aliexpress akan kusan $15 kawai, gami da farashin jigilar kaya. A gefe guda kuma, zaku iya zuwa kantin sayar da Waveshare na hukuma ku nemo shi akan $ 9,99, kodayake dole ne ku ƙara farashin jigilar kaya ...
