ArduinoUNO no board yog raws li ATMega328P ntawm ib tug microcontroller version, download tau nws los muaj hwj chim thiab engineering cov ntaub ntawv kev cob cog rua rau lub computer ntawm ib tug USB cable. Nws muaj 14 cov tswv yim / tso zis, analog tswv yim ports 6, 6 ntawm lawv cov uas yuav siv tau raws li cov tswv yim thiab tso zis ports PWM tso zis, cov tswv yim thiab tso zis ports 14 ntawm nws cov kev khiav hauj lwm voltage yog 5V, thiab tso zis rau ntawm txhua channel can nkag lub siab tshaj plaws tam sim no ntawm 40mA, qhov xyaum ua tej lub sij hawm tsis pub tshaj no tam sim no, thiab cov configuration hauv cov pull-up resistors 20-50K ohms.
