Mini NRF24L01 + Wireless module Mphamvu yowonjezera 2.4G yopanda zingwe ya transceiver module

Zambiri zamalonda

Mafotokozedwe Akatundu
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 Kusankha njira yamagetsi yamagetsi ndi protocol Zikhazikiko zitha kukhazikitsidwa kudzera pa mawonekedwe a SPI Kugwiritsa ntchito pakali pano ndi 9.0mA pomwe mphamvu yotumizira ndi 6dBm munjira yotumizira, 12.3. mA mumalowedwe olandirira, ndipo njira yogwiritsira ntchito panopa ndiyotsika mumayendedwe oima.

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 kuyankhulana 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 magawo onse othamanga kwambiri opangira zizindikiro zokhudzana ndi RF protocol, monga: kubwezeretsanso kwapaketi ya data yotayika ndi chizindikiro chodziwikiratu, ndi zina zotero. MCU kapena kutengera doko la I/O la MCU, ndipo mkati mwake muli MCU.
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 chokonzera kuzindikira kwa chonyamulira, kuzindikirika kwanthawi yayitali komwe kumapangidwira mu hardware CRC kuzindikira zolakwika ndi point-to-multipoint communication adilesi control packet transmission error counter ndi ntchito yozindikira chonyamulira zingagwiritsidwe ntchito pa frequency hop setting zitha kukhazikitsidwa nthawi imodzi kulandira maadiresi a tchanelo, amatha kutsegula njira yolandirira pini ya Dip2.54MM, yosavuta kuyika.
