NRF24L01 ose pusi transceiver pu e tasi o loʻo galue i le 2.4-2.5GHz lautele ISM band. Feavea'i uaealesi e aofia ai: Fa'atupu fa'alava Fa'aleleia le faiga SchockBurstTM Pule fa'aola Malosiaga fa'amalo tioata modulator Demodulator Filifiliga alavai ma protocol E mafai ona fa'atulaga e ala ile SPI feso'ota'iga Fa'atauga o lo'o i ai nei, O le fa'aaogaina o lo'o i ai nei o le 9.0mA pe a 6dBm le mana fa'asalalau, 12.3 mA i le auala e maua ai, ma o le faiga o lo'o i ai nei e maualalo i le tulaga fa'atali.

Tatala le ISM band, tele 0dBm mana fa'asalalau, fa'aoga e leai se laisene. Lagolagoina ala e ono o le mauaina o faamatalaga

1. Maualalo fa'agaioiga voltage: 1.9 ~ 3.6V Low voltage fa'agaioiga
2. Saosaoa maualuga: 2Mbps, ona o le puupuu o le taimi felauaiga ea, fa'aitiitia le fa'alavelave fa'afuase'i i feso'ota'iga uaea (software seti 1Mbps po'o le 2Mbps felauaiga fua faatatau ea)
3. Fa'atele-tele: 125 fa'asologa o taimi e fa'amalie ai mana'oga o feso'ota'iga tele-vaega ma feso'ota'iga fa'asolosolo
4. Ultra-laititi: fausia-i totonu 2.4GHz antenna, laʻititi laʻititi, 15x29mm (e aofia ai antenna)
5. Maualalo le fa'aaogaina o le mana: A'o galue i le tali auala feso'ota'iga, fa'avavevave felauaiga o le ea ma le amataga taimi fa'aitiitia ai le taumafaina o lo'o iai nei.
6. Tau maualalo ole talosaga: NRF24L01 faʻapipiʻi vaega uma o le gaosiga o faʻailoga maualuga e fesoʻotaʻi ma le RF protocol, e pei o le: toe faʻafeiloaʻi otometi o paʻu faʻamatalaga leiloloa ma faʻailoga tali otometi, ma isi. le MCU poʻo faʻataʻitaʻiina e le I / O uafu o le MCU, ma o loʻo i ai se MCU i totonu.
7. Faʻafaigofie ona atiaʻe: Ona o le fesoʻotaʻiga o loʻo faʻapipiʻiina atoatoa i luga o le module, e matua faigofie lava ona atiaʻe. Otometi retransmission galuega, otometi suʻesuʻega ma toetransmission o leiloa faamatalaga packets, toetransmission taimi ma toetransmission taimi e mafai ona pulea e le polokalama e teuina otometi le pepa faamatalaga galuega tali otometi e le maua le faailo tali. A maeʻa ona maua faʻamatalaga faʻamaonia, e otometi lava ona auina atu e le module le faailo tali. Leai se mana'oga e fa'apolokalame le va'aiga va'ava'a a fa'amautu fa'amaumau fa'apipi'i fa'apipi'iina masini fa'apipi'i mea sese CRC ma fa'atonutonu tuatusi feso'ota'iga point-to-multipoint fa'atonuga fa'asalalauga fa'asalalau fa'aputu ma fa'agaioiga va'ava'a e mafai ona fa'aoga mo le fa'asologa o taimi fa'aoso e mafai ona seti i le taimi e tasi ono. mauaina o tuatusi alalaupapa, e mafai ona filifili e tatala le alalaupapa maua masani pine Dip2.54MM pitch interface, faigofie e fa'apipi'i talosaga.
