Mini NRF24L01 + Wireless module Lub zog txhim kho 2.4G wireless transceiver module

Cov ntaub ntawv khoom

Khoom piav qhia
Muab schematics, PID program
NRF24L01 yog ib qho nti transceiver nti ua haujlwm hauv 2.4-2.5GHz universal ISM band. Wireless transceivers muaj xws li: Zaus generator Enhanced SchockBurstTM hom maub los Fais fab amplifier Crystal amplifier modulator Demodulator tso zis hwj chim channel xaiv thiab raws tu qauv teeb tsa los ntawm SPI interface Tsawg noj tam sim no, tam sim no noj yog 9.0mA thaum lub zog kis tau tus mob yog 6dBm nyob rau hauv kis hom, 12.3 mA nyob rau hauv hom tau txais, thiab hom kev noj tam sim no qis dua hauv hom standby.

Qhib ISM band, loj 0dBm kis tau tus mob, daim ntawv tso cai siv dawb. Txhawb rau 6 channel ntawm kev txais cov ntaub ntawv

1. Tsis tshua muaj kev khiav hauj lwm voltage: 1.9 ~ 3.6V Tsawg voltage ua haujlwm
2. Kev kub ceev: 2Mbps, vim lub sij hawm luv luv ntawm huab cua kis tau tus mob, txo qhov kev sib tsoo tshwm sim hauv kev sib kis wireless (software teeb tsa 1Mbps lossis 2Mbps huab cua kis tus nqi)
3. Ntau zaus: 125 zaus cov ntsiab lus kom tau raws li qhov xav tau ntawm kev sib txuas lus ntau thiab kev sib txuas lus ntau zaus
4. Ultra-me: built-in 2.4GHz kav hlau txais xov, me me, 15x29mm (xws li kav hlau txais xov)
5. Kev siv hluav taws xob tsawg: Thaum ua haujlwm hauv kev sib txuas lus teb, kev sib kis ceev ceev thiab lub sijhawm pib ua haujlwm txo qis kev noj tam sim no.
6. Tsawg daim ntawv thov nqi: NRF24L01 integrates tag nrho cov high-ceev teeb liab ua qhov chaw uas muaj feem xyuam rau RF raws tu qauv, xws li: tsis siv neeg retransmission ntawm poob cov ntaub ntawv packets thiab tsis siv neeg teb teeb liab, thiab lwm yam SPI interface ntawm NRF24L01 tuaj yeem txuas los ntawm hardware SPI chaw nres nkoj ntawm MCU lossis simulated los ntawm I / O chaw nres nkoj ntawm MCU, thiab muaj MCU sab hauv.
7. Yooj yim rau kev txhim kho: Vim tias cov txheej txheem txuas tau tag nrho ntawm cov module, nws yooj yim heev los tsim. Tsis siv neeg retransmission muaj nuj nqi, tsis siv neeg tshawb nrhiav thiab rov xa cov ntaub ntawv poob, lub sij hawm xa rov qab thiab lub sij hawm xa rov qab tuaj yeem tswj tau los ntawm software kom cia li khaws cov ntaub ntawv pob ntawv tsis siv neeg teb ua haujlwm uas tsis tau txais cov lus teb. Tom qab tau txais cov ntaub ntawv siv tau, lub module cia li xa cov teeb liab teb. Tsis xav tau kev pab cuam tus cab kuj nrhiav kom tau ib tug ruaj zaus nrhiav kom tau built-in hardware CRC yuam kev nrhiav kom tau thiab point-to-multipoint kev sib txuas lus chaw nyob tswj pob ntawv kis tau tus mob yuam kev counter thiab carrier nrhiav muaj nuj nqi yuav siv tau rau zaus hop chaw yuav teem tib lub sij hawm rau tau txais cov chaw nyob channel, tuaj yeem xaiv qhib qhov tau txais channel tus qauv tus pin Dip2.54MM suab interface, yooj yim rau kev kos daim ntawv thov.
