NRF24L01 waa hal chip transceiver chip oo ka shaqeeya 2.4-2.5GHz band ISM universal. Transceivers Wireless waxaa ka mid ah: Koronto-dhaliyaha soo noqnoqda ee loo yaqaan 'SchockBurstTM mode controller Power amplifier Crystal amplifier modulator Demodulator Output power channel selection and protocol Settings waxaa lagu dejin karaa iyada oo loo marayo SPI interface Isticmaalka hadda hooseeya, Isticmaalka hadda waa 9.0mA marka awoodda gudbintu ay tahay 6dBm ee habka gudbinta, isticmaalka hoose ee 12.3m waa qaabka gudbinta.

Furan ISM band, awood gudbinta 0dBm weyn, isticmaalka shatiga bilaashka ah. Waxay taageertaa lix kanaal oo ah soo dhawaynta xogta

1. Danab yar oo shaqeynaya: 1.9 ~ 3.6V Hawlgallada korantada hooseeya
2. Xawaaraha sare: 2Mbps, iyadoo ay ugu wacan tahay wakhtiga gudbinta hawada oo gaaban, waxa ay si weyn u yaraynaysaa shilalka isku dhaca gudbinta wireless-ka (software dhigay 1Mbps ama 2Mbps heerka gudbinta hawada)
3. Soo noqnoqoshada badan: 125 dhibcood oo soo noqnoqda si loo daboolo baahiyaha isgaadhsiinta dhibcaha badan iyo isgaadhsiinta soo noqnoqda
4. Ultra-yar: anteeno ku dhex dhisan 2.4GHz, cabbir yar, 15x29mm (ay ku jirto anteeno)
5. Isticmaalka tamarta hooseeya: Markaad ku shaqeyneyso habka habka jawaab-celinta, gudbinta hawada degdega ah iyo wakhtiga bilowga waxay si weyn u yareeyaan isticmaalka hadda.
6. Kharashka codsiga hooseeya: NRF24L01 wuxuu isku daraa dhammaan qaybaha xawaaraha sare ee habka signalka ee la xidhiidha nidaamka RF, sida: si toos ah u gudbinta baakidhka xogta lumay iyo calaamad jawaab celin toos ah, iwm. Interface SPI ee NRF24L01 waxaa lagu xiri karaa qalabka SPI ee MCU ama waxaa lagu sawiraa dekedda I / O ee MCU, gudahana waxaa jira MCU.
7. Si fudud loo horumariyo: Sababtoo ah lakabka isku xirka ayaa si buuxda ugu dhex jira moduleka, aad bay u fududahay in la horumariyo. Shaqada dib u gudbinta tooska ah, ogaanshaha tooska ah iyo dib u gudbinta xirmooyinka xogta lumay, wakhtiga dib u gudbinta iyo wakhtiyada dib u gudbinta ayaa lagu xakameyn karaa software si ay si toos ah u kaydiso xirmada xogta shaqada jawaabta tooska ah ee aan helin calaamadda jawaabta. Ka dib markii la helo xog sax ah, cutubku wuxuu si toos ah u soo dirayaa calaamadda jawaabta. Looma baahna in barnaamijka ogaanshaha side ah ogaan inta jeer go'an dhisay-in hardware CRC qalad ogaanshaha iyo dhibic-ilaa-multipoint ciwaanka ciwaanka xakamaynta qalad counter baakidhka gudbinta iyo hawl ogaanshaha side loo isticmaali karaa goobaha hop inta jeer la dhigay karaa waqti isku mid ah lix helaya cinwaanada channel, dooran kartaa furitaanka channel helaya heerka pin Dip2.54MM garoonka interface, fududahay in la rakibo codsiyada.
