RF-Nano yogwirizana ndi ATMEGA328P Nano V3.0 Integrated NRF24L01 opanda zingwe CH340 serial port module

Zoyambitsa Zamalonda:
Chip cha NF24L 01 + chikuphatikizidwa pa bolodi la RF-NANO, ndikupangitsa kuti ikhale ndi ntchito ya transceiver yopanda malire, yomwe ili yofanana ndi kuphatikiza bolodi wamba wa Nano ndi module ya NRF24L01 kukhala imodzi, yomwe ndi yosavuta kugwiritsa ntchito komanso yaying'ono kukula kwake.RF NANO ili ndi zikhomo zofanana ndendende ndi bolodi wamba wa Nano, zomwe zimapangitsa kuti zikhale zosavuta kuziyika.
Zosintha zamalonda:
Kufotokozera kwa purosesa:
Arduino RF-NANO microprocessor ndi ATmega328(Nano3.0), yokhala ndi mawonekedwe a USB-Micro, nthawi yomweyo imakhala ndi 14 digito / zotulutsa 0 (zomwe 6 zitha kugwiritsidwa ntchito ngati kutulutsa kwa PWM), kuyika kwa analogi 8, kristalo wa 16 MHZ. oscillator, Doko la USB-Micro, mutu wa ICSP, ndi batani lokonzanso.
Purosesa: ATmega328
Magetsi ogwiritsira ntchito: 5V Mphamvu yamagetsi (yovomerezeka) : 7-12V Mphamvu yamagetsi (mitundu): 6-20V
Digital I0 pini: 14 (yomwe 6 monga zotuluka za PWM) (D0~D13)
Zikhomo zaanalogi: 6 (A0~A5)
I/O pini DC panopa: 40mA
Memory Memory: 32KB (2KB ya bootloader)
SRAM: 2 KB
EEPROM: 1KB (ATmega328)
USB chosinthira CJ chip: CH340
Nthawi yogwira ntchito: 16 MHz
Magetsi:
Arduino RF-Nano Mphamvu yamagetsi: Micro-USB imalumikizidwa ndi C] magetsi ndipo vin yakunja imalumikizidwa ndi magetsi a 7 ~ 12V akunja a DC.
Memory:
ATmega328 imaphatikizapo 32KB ya on-chip Flash, 2KB ya Boot-loader, 2KB ya SRAM, ndi 1KB ya EEPROM.
Zolowetsa ndi zotuluka:
14 kuyika kwa digito ndi kutulutsa: mphamvu yogwira ntchito ndi 5V, ndipo zotulutsa ndi malire ofikira panjira iliyonse ndi 40mA.Njira iliyonse imapangidwa ndi 20-50K
Ohm mkati kukoka-mmwamba resistor (osalumikizidwa mwachisawawa).Kuphatikiza apo, zikhomo zina zimakhala ndi ntchito zinazake.
Siri chizindikiro RX (No. 0), TX (No. 1) : amapereka TTL voteji mlingo wa siriyo doko analandira chizindikiro, olumikizidwa kwa FT232RI lolingana pini.
Zosokoneza zakunja (No. 2 ndi 3) : Yambitsani pini yosokoneza, yomwe ikhoza kukhazikitsidwa kuti ikwere m'mphepete, m'mphepete, kapena zonse ziwiri.
Pulse wide modulation PWM (3, 5, 6, 9, 10, 11) : imapereka zotuluka 6 8-bit PWM.
SPI (10(SS), 11(MOSI), 12(MISO), 13(SCK)): SPI communication interface.
LED (No. 13) : Arduino yapadera) imagwiritsidwa ntchito kuyesa mawonekedwe osungira l_ED.Kuwala kwa LED kumayatsidwa pamene kutulutsa kuli kwakukulu, ndipo LED imazimitsidwa pamene kutulutsa kuli kochepa.
Zolowetsa 6 za analogi A0 mpaka A5: Iliyonse - njira ili ndi malingaliro a 10 bits (ndiko kuti, zolowetsazo zimakhala ndi 1024 zosiyana), mtundu wa siginecha wokhazikika ndi 0 mpaka 5V, ndipo malire apamwamba amatha kusinthidwa ndi AREF.Kuphatikiza apo, zikhomo zina zimakhala ndi ntchito zinazake.
TWI mawonekedwe (SDA A4 ndi SCL A5) : Imathandizira mawonekedwe olankhulirana (yogwirizana ndi I2C basi).
AREF: Mphamvu yowunikira ya siginecha ya analogi.
Kulumikizana:
Doko la seri: UART yomangidwa mkati ya ATmega328 imatha kulumikizana ndi madoko akunja kudzera pamadoko a digito 0 (RX) ndi 1 (TX).
