RF-Nano hototahi ki ATMEGA328P Nano V3.0 Integrated NRF24L01 ahokore CH340 kōwae tauranga rangatū

Hua Whakataki:
Ko te maramara NF24L 01+ kua whakauruhia ki runga i te papa o te RF-NANO, he mea he mahi whakawhiti kore mutunga, he rite ki te whakakotahi i te papa Nano noa me te NRF24L01 kōwae ki te kotahi, he pai ake te whakamahi me te iti o te rahi. Ko te RF NANO he rite tonu nga titi ki te papa Nano noa, he ngawari ki te whakawhiti.
Tawhā hua:
Whakaahuatanga pūtukatuka:
Arduino RF-NANO microprocessor ko ATmega328(Nano3.0), me te USB-Micro atanga, i te wa ano he 14 mamati whakauru / putanga 0 (e 6 ka taea te whakamahi hei putanga PWM), 8 whakauru tairitenga, he karaihe 16 MHZ oscillator, He tauranga USB-Micro, he pane ICSP, me te paatene tautuhi.
Tukatuka: ATmega328
Ngaohiko mahi: 5V Ngaohiko whakauru (e taunakitia ana) : 7-12V Ngaohiko whakauru (awhe) : 6-20V
Mamati I0 titi: 14 (e 6 hei putanga PWM) (D0~D13)
titi tāuru tairitenga: 6 (A0~A5)
I/O titi DC nāianei: 40mA
Mahara Kohiko: 32KB (2KB mo te utauta)
SRAM: 2KB
EEPROM: 1KB (ATmega328)
Kaitahuri USB maramara CJ: CH340
Karaka mahi: 16 MHZ
Tuku Hiko:
Arduino RF-Nano Power supply: Kei te hono te Micro-USB ki te C] te mana hiko me te vin o waho e hono ana ki te 7 ~ 12V waho DC mana hiko
Pūmahara:
Kei roto i te ATmega328 te 32KB o te Flash maramara, 2KB mo te Boot-loader, 2KB o te SRAM, me te 1KB o te EEPROM.
Whakauru me te putanga:
14 te whakaurunga me te whakaputanga mamati: ko te ngaohiko mahi he 5V, ko te putanga me te tepe uru o ia hongere he 40mA. Kua whirihorahia ia hongere me te 20-50K
Ohm parenga kume-ake o roto (kaore e hono taunoa). I tua atu, he mahi motuhake etahi o nga titi.
Tohu rangatū RX (No. 0), TX (No. 1): whakarato TTL taumata ngaohiko o te tauranga rangatū riro tohu, hono ki te FT232RI titi hāngai.
Nga haukoti o waho (Nama. 2 me te 3) : Whakaohohia te titi haukoti, ka taea te whakarite ki te ara ake, ki te taha hinga, ki te rua ranei.
Whakarereketanga whanui PWM (3, 5, 6, 9, 10, 11): whakarato 6 8-bit PWM putanga.
SPI (10(SS), 11(MOSI), 12(MISO), 13(SCK)): Atanga whakawhitiwhiti SPI.
LED (No. 13): Ko Arduino motuhake) ka whakamahia hei whakamatautau i te atanga pupuri o l_ED. Ka tahuna te LED i te wa e teitei ana te whakaputanga, a ka tineia te LED ina iti te putanga.
E 6 nga whakaurunga tairitenga A0 ki te A5: Ko ia – te hongere he taumira 10 moka (ara, ko te whakaurunga he 1024 nga uara rereke), ko te awhe tohu whakauru taunoa ko te 0 ki te 5V, a ka taea e te AREF te whakatika te rohe o runga whakauru. I tua atu, he mahi motuhake etahi o nga titi.
Atanga TWI (SDA A4 me SCL A5) : Ka tautoko i te atanga korero (hototahi ki te pahi I2C).
AREF: Te ngaohiko tohutoro o te tohu whakauru tairitenga.
Atanga whakawhitiwhiti:
Tauranga Rangatū: Ka taea e te UART hangaia o te ATmega328 te whakawhitiwhiti korero me nga tauranga rangatū o waho na roto i nga tauranga mamati 0 (RX) me te 1 (TX).
