Mini NRF24L01+ Wireless module Simba rakawedzerwa 2.4G isina waya transceiver module

Product information

Chigadzirwa tsananguro
Ipa schematics, chirongwa chePID
NRF24L01 ndeye imwechete chip transceiver chip inoshanda mu 2.4-2.5GHz universal ISM bhendi. Wireless transceivers dzinosanganisira: Frequency generator Enhanced SchockBurst TM mode controller Power amplifier Crystal amplifier modulator Demodulator Output power channel sarudzo uye protocol Zvirongwa zvinogona kuiswa kuburikidza neSPI interface Kuderedza kushandiswa kwezvino, Iko kushandiswa ikozvino 9.0mA apo simba rekutumira riri 6dBm mukutumira mode, 12.3. mA mune yekugamuchira modhi, uye yazvino yekushandisa modhi yakaderera mune yekumira mode.

Vhura ISM bhendi, hombe 0dBm yekufambisa simba, rezinesi rekushandisa mahara. Inotsigira nhanhatu nzira dzekugamuchira data

1. Low kushanda voltage: 1.9 ~ 3.6V Low voltage kushanda
2. High speed: 2Mbps, nekuda kwenguva pfupi yekufambisa mhepo, inoderedza zvikuru chiitiko chekudhumhana mukutumira kusina wireless (software set 1Mbps kana 2Mbps air transmission rate)
3. Multi-frequency: 125 frequency point kuti isangane nezvinodiwa zvemulti-point kutaurirana uye frequency-hopping kutaurirana.
4. Ultra-diki: yakavakirwa-mukati 2.4GHz antenna, diki saizi, 15x29mm (kusanganisira antenna)
5. Kuderedza simba rekushandisa: Paunenge uchishanda mukupindura maitiro ekukurukurirana, kukurumidza kufambisa mhepo uye nguva yekutanga inoderedza zvikuru kushandiswa kwemazuva ano.
6. Mari yekushandiswa yakaderera: NRF24L01 inobatanidza zvikamu zvose zvepamusoro-soro zvekugadzirisa zviratidzo zvine chokuita neRF protocol, zvakadai se: otomatiki retransmission yeakarasika data packets uye automatic response signal, etc. SPI interface yeNRF24L01 inogona kubatanidzwa ne hardware SPI port ye iyo MCU kana inoteedzerwa neI / O chiteshi cheMCU, uye mukati mune MCU.
7. Zviri nyore kukudziridza: Nokuti iyo link layer yakanyatsobatanidzwa pane module, zviri nyore kwazvo kukudziridza. Otomatiki retransmission basa, kuona otomatiki uye kudzoreredza kweakarasika data packet, nguva yekudzorera uye nguva yekudzorera inogona kudzorwa nesoftware kuti ichengetedze otomatiki data pakiti otomatiki mhinduro isingagamuchire chiratidzo chekupindura. Mushure mekugamuchira data inoshanda, module inotumira otomatiki chiratidzo chekupindura. Hapana chikonzero chekuronga mutakuri wekuona iyo yakagadziriswa frequency yekuona yakavakirwa-mukati hardware CRC yekuona kukanganisa uye point-to-multipoint kutaurirana kero control packet transmission error counter uye mutakuri wekuona basa anogona kushandiswa frequency hop kuseta inogona kusetwa panguva imwe chete yechitanhatu. kugamuchira kero dzechiteshi, inogona kusarudza kuvhura iyo yekugamuchira chiteshi pini Dip2.54MM pitch interface, iri nyore kuisirwa maapplication.
