Mirayiridzo:

<1>: simba

Kuseri kwemodule inoenderana nechiteshi GND, uye 3.7V yakabatanidzwa kune yakaipa uye yakanaka materminals emagetsi (bhatiri) zvichiteerana. Simba remagetsi rinokurudzirwa kushandisa bhatiri kana transformer nhanho-pasi yakagadziriswa magetsi. Usashandise magetsi ekuchinja pasina mafirita (semachaja enharembozha, mabhanga emagetsi, kushandura magetsi eDC-DC), zvimwe, iyo yepamusoro-frequency kupindira inogadzirwa nechikamu chemagetsi chinozokanganisa kushanda kwakajairika kweiyo module. Iyo yakajairika kushanda voltage yeiyi module ndeye 3.0-5.0V, uye magetsi emagetsi haafaniri kudarika aya.

<2>: kanyanga

Iyo ANT port inoshandiswa kubatanidza iyo FM antenna. Kuti utumire zvirinani masaini eFM, inokurudzirwa kubatanidza 75cm-yakareba chikwapu antenna, uye hapafanirwe kuve nezvipingamupinyi sezvinobvira pedyo neantenna.

<3>: Frequency kugadzirisa

Iyi module inoda kushandisa komputa kugadzirisa radio frequency point yayo (tarisa kune frequency kumisikidza nzira muchikamu chezasi chepeji yeruzivo rweiyo chaiyo nzira yekushanda).

Nyaya dzinoda kutarisirwa:

1: Ndokumbira usimbise kuti magetsi ekupa polarity uye magetsi emagetsi ndizvozvo usati wabatidza magetsi. Kana iyo yekupinza voltage inodarika 5V kana matanda akanaka uye asina kunaka emagetsi emagetsi akabatana nekudzosera, inogona kukonzera kukuvara zvachose kune module.

2: Usabate zvikamu zvekumashure zvemodule paunenge uchishanda, kuitira kuti usakanganise kushanda kwakajairwa kwemodule.

Shandura tsananguro yekunzwa maikorofoni:

Iyi module inogona kushandura maikorofoni yekutora senitivity nekugadzirisa iyo isina kunaka mhinduro kuramba yemakrofoni preamplifier wedunhu., kuitira kuti isangane nekugadziriswa kwevashandisi vega kune zvakakosha zvekunzwa zvinodiwa. Iyo fekitori yekusarudzika kukosha kweiyo yakaipa mhinduro kuramba maikorofoni preamplifier ndeye 82K ohms. Kuwedzera kupikisa uku kunowedzera kunzwisiswa kwemaikorofoni uku ichideredza kuramba uku kunoderedza kunzwisiswa kwemakrofoni.. chitsamba: Isu tinongopa nzira yekuchinja. Kana uchida kuichinja, ndokumbirawo uzvitengere uye uzvigadzirise iwe pachako. Zvese zvinotakurwa zvinobva pane iyo default senitivity. Isu hatishandure sensitivity parameters kumutengi wega wega.

Frequency kumisikidza nzira uye maitiro:

1: USB kuTTL module uye iyo module yekubatanidza nzira

(2): batanidza iyo USB kune serial port module uye module mushure mekuiswa kwe USB kune serial module pakombuta, kumirira kuti mutyairi azviise otomatiki mushure mekuiswa kwapera otomatiki vhura iyo mudziyo maneja kuti uone USB kune TTL module inoenderana serial port nhamba.
