Mini NRF24L01 + Wireless module Imbaraga zongerewe 2.4G module ya transceiver module

Amakuru y'ibicuruzwa

Ibisobanuro ku bicuruzwa
Tanga ibishushanyo, gahunda ya PID
NRF24L01 ni chip imwe ya chip transceiver chip ikorera muri bande ya ISM ya 2.4-2.5GHz. Umuyoboro udafite insinga zirimo: Umuyoboro wa Frequency Enhanced SchockBurstTM moderi igenzura Imbaraga amplifier Crystal amplifier modulator Demodulator Ibisohoka byumuyoboro wamashanyarazi hamwe na protocole Igenamiterere rishobora gushyirwaho hifashishijwe interineti ya SPI Imikoreshereze mike iriho, Ibikoreshwa muri iki gihe ni 9.0mA mugihe imbaraga zo kohereza ari 6dBm muburyo bwo kohereza, 12.3 mA muburyo bwo kwakira, kandi uburyo bwo gukoresha buri hasi muburyo bwo guhagarara.

Fungura itsinda rya ISM, nini ya 0dBm yohereza, uruhushya rwo gukoresha kubuntu. Shyigikira imiyoboro itandatu yo kwakira amakuru

1. Umuvuduko muke muke: 1.9 ~ 3.6V Igikorwa gito cya voltage
2. Umuvuduko mwinshi: 2Mbps, kubera igihe gito cyo kohereza ikirere, gabanya cyane ibintu byo kugongana mugukwirakwiza bidasubirwaho (software yashyizeho 1Mbps cyangwa 2Mbps yohereza ikirere)
3. Umuyoboro mwinshi: amanota 125 yumurongo kugirango uhuze ibikenewe byitumanaho ryinshi hamwe nitumanaho ryihuta
4. Ultra-nto: yubatswe muri antenne ya 2.4GHz, ubunini buto, 15x29mm (harimo na antene)
5. Gukoresha ingufu nke: Iyo ukora muburyo bwo gutumanaho uburyo bwo gusubiza, kohereza ikirere byihuse nigihe cyo gutangira bigabanya cyane ibyo ukoresha ubu.
6. Igiciro gito cyo gusaba: NRF24L01 ihuza ibice byose byihuta byogutunganya ibimenyetso bijyanye na protocole ya RF, nka: gusubiza mu buryo bwikora paki yatakaye hamwe nibimenyetso byogusubiza, nibindi. Imigaragarire ya SPI ya NRF24L01 irashobora guhuzwa nicyambu cya SPI cyicyuma cya MCU cyangwa bigereranywa nicyambu cya I / O cya MCU, kandi imbere hari MCU.
7. Biroroshye kwiteza imbere: Kuberako ihuza ryuzuye ryuzuye kuri module, biroroshye cyane kwiteza imbere. Igikorwa cyo gusubiza mu buryo bwikora, gutahura mu buryo bwikora no kohereza amakuru yatakaye, igihe cyo gusubiza hamwe nigihe cyo kohereza gishobora kugenzurwa na software kugirango ihite ibika data packet ibikorwa byikora bidasubirwaho bitakira ibimenyetso byo gusubiza. Nyuma yo kwakira amakuru yemewe, module ihita yohereza ikimenyetso cyo gusubiza. Ntibikenewe ko porogaramu itwara abagenzi itondekanya inshuro zagenwe zubatswe mu byuma bya CRC gutahura ikosa no gutondekanya amakuru kuri aderesi y'itumanaho igenzura ipaki yohereza ikosa hamwe nigikorwa cyo gutahura abatwara ibintu bishobora gukoreshwa mugihe cyo gushiraho inshuro nyinshi bishobora gushyirwaho icyarimwe gatandatu kwakira umuyoboro wa aderesi, urashobora guhitamo gufungura imiyoboro yakira pin Dip2.54MM ikibanza cyoroshye, byoroshye gushyiramo porogaramu.
