Perekani schematics, pulogalamu ya PID
NRF24L01 ndi chip transceiver chip chimodzi chomwe chimagwira ntchito mu 2.4-2.5GHz universal ISM band. Ma transceivers opanda zingwe akuphatikizapo: Frequency jenereta Yowonjezera SchockBurst TM mode controller Power amplifier Crystal amplifier modulator Demodulator Kusankhidwa kwa njira ya mphamvu yamagetsi ndi protocol Zikhazikiko zikhoza kukhazikitsidwa kudzera mu mawonekedwe a SPI Kugwiritsa ntchito pakali pano ndi 9.0mA pamene mphamvu yotumizira ndi 6dBm mu njira yotumizira, 12mA yogwiritsira ntchito mode ndi 3mA yotsika mumode.

Tsegulani gulu la ISM, mphamvu yayikulu yotumizira 0dBm, kugwiritsa ntchito kwaulere. Imathandizira njira zisanu ndi imodzi zolandirira deta

1. Kutsika kwamagetsi ogwiritsira ntchito: 1.9 ~ 3.6V Opaleshoni yotsika yamagetsi
2. Liwiro lalikulu: 2Mbps, chifukwa cha nthawi yochepa yotumizira mpweya, kuchepetsa kwambiri kugunda chodabwitsa mu kufala opanda zingwe (mapulogalamu anapereka 1Mbps kapena 2Mbps mpweya kufala mlingo)
3. Multi-frequency: 125 ma frequency point kuti akwaniritse zosowa za kulumikizana kwamitundu yambiri komanso kulumikizana pafupipafupi
4. Kang'ono kwambiri: mlongoti womangidwa mu 2.4GHz, kukula kochepa, 15x29mm (kuphatikiza mlongoti)
5. Kugwiritsa ntchito mphamvu zochepa: Pamene mukugwira ntchito poyankhira njira yoyankhira, kutumiza mpweya wothamanga ndi nthawi yoyambira kumachepetsa kwambiri kugwiritsa ntchito panopa.
6. Mtengo wotsika mtengo: NRF24L01 imagwirizanitsa mbali zonse zazitsulo zothamanga kwambiri zokhudzana ndi RF protocol, monga: kubwezeretsanso kwapaketi ya data yotayika ndi chizindikiro chodziwikiratu choyankhira, etc. Mawonekedwe a SPI a NRF24L01 akhoza kulumikizidwa ndi doko la hardware la SPI la MCU kapena lofanana ndi doko la I / O la MCU, ndipo pali MCU mkati.
7. Zosavuta kupanga: Chifukwa chosanjikiza cholumikizira chikuphatikizidwa kwathunthu pa module, ndizosavuta kupanga. Ntchito yobwezeretsanso yodziwikiratu, kudziwikiratu komanso kutumiziranso mapaketi otayika a data, nthawi yotumiziranso nthawi komanso nthawi zotumiziranso zitha kuwongoleredwa ndi mapulogalamu kuti asungiretu paketi ya data yodziwikiratu ntchito yomwe siyilandira chizindikiro choyankha. Pambuyo polandira deta yovomerezeka, gawoli limangotumiza chizindikiro choyankha. Palibe chifukwa chowonera chonyamulira chodziwikiratu chokhazikika chodziwikiratu chomwe chidamangidwa mu hardware CRC kuzindikira zolakwika ndi point-to-multipoint adilesi yowongolera paketi yopatsira zolakwika ndi chonyamulira cholumikizira chingagwiritsidwe ntchito pafupipafupi kadumphidwe kadumphidwe katha kukhazikitsidwa nthawi imodzi maadiresi asanu ndi limodzi olandila, amatha kusankha njira yolandirira pini yokhazikika ya Dip2.54MM, yosavuta kuyika mapulogalamu.
