Zvinhu Gumi Zvekufunga Kana Uchitenga Bluetooth Module
Kunyangwe pari zvino kune akawanda maBluetooth module ehukuru hwakasiyana nemhando pamusika kusarudza kubva, vazhinji vagadziri vezvishandiso vakangwara vanonetsekana nekusarudza Bluetooth module inokodzera zvigadzirwa zvavo. Muchokwadi, kana uchitenga a Bluetooth module , zvinonyanya kuenderana nechigadzirwa chaunogadzira uye mamiriro ayo anoshandiswa.
Pazasi, Joinet inopfupikisa izvo zvepamusoro zvinhu gumi zvekuteerera kana uchitenga maBluetooth module ekunongedza kwevazhinji veIoT vanogadzira zvishandiso.
Zvinhu zvekucherekedza kana uchitenga Bluetooth module
1. Chip
Iyo chip inosarudza simba rekombuta reBluetooth module. Pasina "core" yakasimba, kuita kweBluetooth module hakugone kuvimbiswa. Kana ukasarudza yakaderera-simba Bluetooth module, ari nani machipi anosanganisira Nordic, Ti, nezvimwe.
2. Kudya simba
Bluetooth yakakamurwa kuita yechinyakare Bluetooth uye yakaderera-simba Bluetooth. Zvishandiso zvine hungwaru zvinoshandisa zvechinyakare mamodule eBluetooth zvinogara zvichidimburwa uye zvinoda kudzokororwa pairings, uye bhatiri rinopera nekukurumidza. Zvishandiso zvine hungwaru zvinoshandisa yakaderera-simba maBluetooth modules zvinongoda pairing imwe chete. Bhatani rimwe bhatani rinogona kushanda kwenguva yakareba. Naizvozvo, kana uri kushandisa bhatiri-powered waya isina waya smart kifaa, zviri nani kushandisa Bluetooth 5.0/4.2/4.0 yakaderera-simba Bluetooth module kuti uve nechokwadi chechigadzirwa.’s hupenyu hwebhatiri.
3. Transmission content
Iyo Bluetooth module inogona kufambisa isina waya data uye ruzivo rwezwi. Yakakamurwa kuita Bluetooth data module uye Bluetooth izwi module zvinoenderana nebasa rayo. Iyo Bluetooth data module inonyanya kushandiswa pakufambisa data, uye inokodzera ruzivo uye kuendesa data munzvimbo dzeveruzhinji dzine traffic yakakura senge mashoo, zviteshi, zvipatara, masikweya, nezvimwe; iyo Bluetooth voice module inogona kufambisa ruzivo rwezwi uye inokodzera kutaurirana pakati peBluetooth mbozha nhare uye Bluetooth mahedhifoni. Kufambiswa kwemashoko ezwi.
4. Transmission rate
Paunosarudza Bluetooth module, iwe unofanirwa kuve wakajeka nezve mashandisirwo eBluetooth module, uye shandisa iyo data yekufambisa chiyero inodiwa pasi pemamiriro ekushanda seyero yekusarudza. Mushure mezvose, chiyero che data chinodiwa kuendesa mimhanzi yemhando yepamusoro kumahedhifoni yakasiyana neyekurova kwemoyo. Nhamba dzinodiwa dze data dzinosiyana zvakanyanya.
5. Transmission distance
Vagadziri vemidziyo yeIoT vanofanirwa kunzwisisa nharaunda umo zvigadzirwa zvavo zvinoshandiswa uye kana yavo isina waya yekufambisa kureba zvinodiwa zvakakwirira. Kune zvigadzirwa zvisina waya zvisingade yakakwira isina waya yekufambisa kureba, senge mbeva dzisina waya, mahedhifoni asina waya, uye madhiraivha ari kure, unogona kusarudza mamodule eBluetooth ane chinhambwe chekutumira chinodarika mamita gumi; kune zvigadzirwa zvisingade yakakwira isina waya yekufambisa kureba, senge yekushongedza RGB mwenje, unogona kusarudza Iyo yekufambisa kureba inodarika 50 metres.
6. Packaging fomu
Kune marudzi matatu eBluetooth modules: yakananga plug-in mhando, yepamusoro-gomo mhando uye serial port adapter. Iyo yakananga-plug mhando ine mapini, ayo ari nyore kune ekutanga soldering uye akakodzera diki kugadzirwa batch; iyo yepamusoro-yakaiswa module inoshandisa semi-denderedzwa pads sepini, iyo yakakodzera yakakura-vhoriyamu reflow soldering kugadzirwa kwezvidiki zvitakuri; iyo serial Bluetooth adapta inoshandiswa Kana zvisingaite kuvaka Bluetooth mumudziyo, unogona kuiisa zvakananga mupfumbamwe-pini serial port yemuchina uye inogona kushandiswa pakarepo mushure mekuisa simba.
7. Interface
Zvichienderana nezvinodiwa zvemashandisirwo emabasa chaiwo akaitwa, mainterface eBluetooth module akakamurwa kuita serial interfaces, USB interfaces, dijitari IO ports, analog IO ports, SPI programming ports uye izwi rekupindirana. Imwe neimwe interface inogona kuita akasiyana anoenderana mabasa. . Kana ichingori kuendesa data, ingo shandisa serial interface (TTL level).
8. Tenzi-muranda ukama
Iyo master module inogona kushingaira kutsvaga uye kubatanidza mamwe maBluetooth modules ane imwechete kana kudzika Bluetooth version level pane pachayo; iyo muranda module inongomirira kuti vamwe vatsvage uye vabatanidze, uye iyo Bluetooth vhezheni inofanira kunge yakafanana kana yakakwirira kupfuura yayo. Zvishandiso zvakawanda zvakangwara pamusika zvinosarudza mamodule evaranda, nepo master modules achiwanzo shandiswa pamidziyo yakadai senharembozha dzinogona kushanda senzvimbo dzekudzora.
9. Antenna
Zvigadzirwa zvakasiyana zvine zvakasiyana zvinodiwa kune antennas. Parizvino, antenna anonyanya kushandiswa eBluetooth modules anosanganisira PCB antennas, ceramic antennas uye IPEX ekunze antennas. Kana akaiswa mukati mekugara kwesimbi, maBluetooth modules ane IPEX ekunze antennas anowanzo kusarudzwa.
10. Mutengo-kubudirira
Mutengo ndiyo inonyanya kunetseka kune vazhinji vagadziri veIoT mudziyo
Joinet yanga ichibatanidzwa zvakanyanya mumunda wepasi-simba maBluetooth modules kwemakore mazhinji. Muna 2008, yakava mupi anofarirwa wemakambani epamusoro mazana mashanu epasirese. Iyo ine pfupi pfupi stocking kutenderera uye inogona kukurumidza kupindura kune zvakasiyana zvinodiwa zvevazhinji vevagadziri vemidziyo. Iyo kambani iripo yekugovera cheni uye mitsara yekugadzira inogona kuwana zviri pachena zvakanakira mutengo, kuve nechokwadi chekuti ruzhinji rwevagadziri vemidziyo vanogona kushandisa yakaderera-inodhura, inodhura-yakaderera-simba maBluetooth module. Pamusoro pezvinofungidzirwa gumi zviri pamusoro, vagadziri vezvishandiso vanofanirwawo kunzwisisa saizi, kugamuchira kunzwa, simba rekutapurirana, Flash, RAM, nezvimwe. yeBluetooth module paunenge uchitenga Bluetooth module.
