NRF24L01 waa hal chip transceiver chip oo ka shaqeeya 2.4-2.5GHz band ISM universal.Transceivers Wireless-ka waxaa ka mid ah: Koronto-dhaliyaha soo noqnoqda ee loo yaqaan 'SchockBurst TM' kontorooliyaha korantada korantada Crystal amplifier modulator Demodulator Output power channel xulashada iyo habraaca habraaca waxaa lagu dejin karaa iyada oo loo marayo interface SPI Isticmaalka hadda hooseeya, Isticmaalka hadda waa 9.0mA marka awoodda gudbintu ay tahay 6dBm habka gudbinta, 12.3 mA habka helida, iyo qaabka isticmaalku hadda wuu ka hooseeyaa qaabka heeganka.

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 borotokoolka RF, sida: dib u gudbinta tooska ah ee xirmooyinka xogta lumay iyo calaamad jawaab celin toos ah, iwm. Interface SPI ee NRF24L01 waxaa lagu xiri karaa qalabka SPI ee dekedda. MCU ama waxaa lagu sawiray dekedda I/O ee MCU, waxaana gudaha MCU ku yaal.
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 sidaha ogaanshaha soo noqnoqoshada go'an oo ku dhex dhisan hardware CRC ogaanshaha qaladka iyo ciwaanka-ilaa-pup-to-multipoint ciwaanka xakamaynta qaladka gudbinta baakidhka iyo shaqada ogaanshaha waxa loo isticmaali karaa goob hop-frequency la dejin karaa isla mar lix Helitaanka ciwaannada kanaalka, waxay si xushmad leh u furi kartaa kanaalka helaya heerka pin Dip2.54MM interface garoonka, fududahay in la rakibo codsiyada.
