I-RF-Nano iyahambisana ne-ATMEGA328P Nano V3.0 Integrated NRF24L01 wireless CH340 serial port module

Isingeniso Somkhiqizo:
I-chip ye-NF24L 01+ ihlanganiswe ebhodini le-RF-NANO, okwenza ibe nomsebenzi we-transceiver ongenamkhawulo, okulingana nokuhlanganisa ibhodi le-Nano elijwayelekile kanye nemojula ye-NRF24L01 ibe yinye, elula kakhulu ukuyisebenzisa futhi encane ngosayizi. I-RF NANO inamaphini afana ncamashí nebhodi le-Nano elivamile, okwenza kube lula ukulitshala.
Amapharamitha womkhiqizo:
Incazelo yephrosesa:
I-microprocessor ye-Arduino RF-NANO yi-ATmega328(Nano3.0), ene-interface ye-USB-Micro, ngesikhathi esifanayo inokufakwayo/okuphumayo kwedijithali okungu-14 0 (okungu-6 kwakho kungasetshenziswa njengokuphuma kwe-PWM), okokufaka kwe-analog okungu-8, ikristalu engu-16 MHZ. i-oscillator, Imbobo ye-USB-Micro, unhlokweni we-ICSP, nenkinobho yokusetha kabusha.
Iprosesa: ATmega328
I-voltage esebenzayo: 5V I-voltage yokufaka (kuyanconywa) : 7-12V I-voltage yokufaka (ububanzi) : 6-20V
Iphinikhodi ye-Digital I0: 14 (okukhona okungu-6 njengokuphumayo kwe-PWM) (D0~D13)
Izikhonkwane zokufakwayo kwe-analogi: 6 (A0~A5)
I/O pin DC current: 40mA
Imemori Ye-Flash: 32KB (2KB ye-bootloader)
I-SRAM: 2KB
I-EEPROM: 1KB (ATmega328)
Isiguquli se-USB CJ chip: CH340
Iwashi lokusebenza: 16 MHZ
Ukunikezwa kwamandla kagesi:
I-Arduino RF-Nano Power supply: I-Micro-USB ixhunywe ku-C] amandla kagesi kanye ne-vin yangaphandle ixhumeke ku-7 ~ 12V yangaphandle kagesi ye-DC
Inkumbulo:
I-ATmega328 ifaka phakathi u-32KB we-on-chip Flash, u-2KB we-Boot-loader, u-2KB we-SRAM, no-1KB we-EEPROM.
Okokufaka nokuphumayo:
14 okokufaka nokuphumayo kwedijithali: amandla kagesi asebenzayo yi-5V, kanti amandla okukhipha kanye nomkhawulo wokufinyelela wesiteshi ngasinye ngu-40mA. Isiteshi ngasinye silungiselelwe ngo-20-50K
I-Ohm yangaphakathi yokudonsa-up resistor (ayixhunyiwe ngokuzenzakalelayo). Ngaphezu kwalokho, ezinye izikhonkwane zinemisebenzi ethile.
Isiginali ye-serial RX (No. 0), TX (No. 1) : ihlinzeka ngezinga le-voltage ye-TTL yesiginali ye-serial eyamukelwe, exhunywe kuphinikhodi ehambisanayo ye-FT232RI.
Iziphazamiso zangaphandle (No. 2 kanye no-3) : Qalisa iphinikhodi yokuphazamisa, engasethwa ukuthi inyuke, ishone emaphethelweni, noma kokubili.
Ukuguquguquka kobubanzi be-Pulse PWM (3, 5, 6, 9, 10, 11) : inikeza okuphumayo okungu-6 8-bit PWM.
I-SPI (10(SS), 11(MOSI), 12(MISO), 13(SCK)) : Isikhombi sokuxhumana se-SPI.
I-LED (No. 13) : I-Arduino ekhethekile) isetshenziselwa ukuhlola isixhumi esibonakalayo sokugcinwa kwe-l_ED. I-LED ikhanya lapho okukhiphayo kuphezulu, futhi i-LED iyacima lapho okukhiphayo kuphansi.
6 okokufaka kwe-analog A0 kuya ku-A5: Isiteshi ngasinye sinesixazululo samabhithi ayi-10 (okungukuthi, okokufaka kunamanani ahlukene we-1024), uhla lwesiginali yokufaka oluzenzakalelayo luyi-0 kuya ku-5V, futhi umkhawulo ongaphezulu wokufakwayo ungalungiswa yi-AREF. Ngaphezu kwalokho, ezinye izikhonkwane zinemisebenzi ethile.
I-interface ye-TWI (i-SDA A4 ne-SCL A5): Isekela isixhumi esibonakalayo sokuxhumana (ihambisana nebhasi le-I2C).
I-AREF: I-voltage eyireferensi yesiginali yokufaka ye-analog.
Isixhumi esibonakalayo sokuxhumana:
Imbobo ye-serial: I-UART eyakhelwe ngaphakathi ye-ATmega328 ingaxhumana nezimbobo ze-serial zangaphandle ngokusebenzisa izimbobo zedijithali 0 (RX) kanye no-1 (TX).
