Arduino boards siv SRAM (Static Random-Access Memory). Cov Mega 2560 muaj qhov chaw SRAM feem ntau nrog 8 kB, uas yog 4x ntau tshaj qhov Uno , thiab 3.2x ntau dua Micro. Nrog ntau qhov chaw SRAM, lub Arduino muaj ntau qhov chaw los tsim thiab tswj cov kev hloov pauv thaum nws khiav.
Ib yam li ntawd, peb puas tuaj yeem siv Arduino Uno hloov Arduino Mega?
Cov Uno txawv ntawm tag nrho cov boards ua ntej nyob rau hauv uas nws tsis siv FTDI USB-rau-serial tsav nti. Hloov chaw , nws nta Atmega16U2 (Atmega8U2 mus txog version R2) programmed li USB-rau-serial converter. Cov Arduino Mega 2560 yog microcontroller board raws li ATmega2560 (datasheet).
Tsis tas li ntawd, vim li cas Arduino Uno zoo dua? Ib txhia ntawm nws zoo dua nta yog: Nws qhov txiaj ntsig loj tshaj plaws yog tias peb txuas lub rooj tsavxwm rau lub khoos phis tawj ntawm USB cable uas ua ob lub hom phiaj ntawm kev muab lub zog thiab ua raws li Serial chaw nres nkoj los cuam tshuam cov Arduino thiab lub computer. Nws tseem tuaj yeem siv los ntawm 9V-12V AC rau DC adapter.
Tsuas yog li ntawd, dab tsi yog qhov haib tshaj Arduino?
Arduino UNO Lub UNO yog arguably qhov nrov tshaj plaws Arduino. Nws yog siv los ntawm Atmega328 processor kev khiav hauj lwm ntawm 16MHz, suav nrog 32KB ntawm kev pab cuam nco, 1KB ntawm EEPROM, 2KB ntawm RAM, muaj 14 digital I/O, 6 analog inputs, thiab ob qho tib si 5V thiab 3.3V fais fab rails.
Qhov twg zoo dua Arduino Nano lossis Uno?
Qhov sib txawv tseem ceeb ntawm ob qho no yog qhov loj. Vim Arduino Ib qhov loj yog ob npaug rau nano lub rooj tsavxwm. Yog li Uno boards siv ntau qhov chaw ntawm lub system. Programming ntawm UNO tuaj yeem ua tiav nrog USB cable whereas Nano siv lub mini USB cable.
