Iziyalezo:

<1>: Power

Ingemuva lemojuli ihambisana nechweba GND, futhi i-3.7V ixhunywe kumatheminali anegethivu kanye nephozithivu yokuphakelwa kukagesi (ibhethri) ngokulandelana. Ukunikezwa kwamandla kuyanconywa ukuthi kusetshenziswe ibhethri noma isiguquli sikagesi esilawulwa ngokusuka phansi. Ungasebenzisi izinto zokushintsha amandla ngaphandle kwezihlungi (njengamashaja omakhalekhukhwini, amabhange kagesi, ukushintsha amandla kagesi e-DC-DC), kungenjalo, ukuphazamiseka kwe-high-frequency okukhiqizwa yingxenye yokuphakelwa kwamandla kuzothinta ukusebenza okuvamile kwale mojula. I-voltage evamile yokusebenza yale module ingu-3.0-5.0V, futhi i-voltage yokuphakela amandla akufanele yeqe lobu bubanzi.

<2>: Antenna

Imbobo ye-ANT isetshenziselwa ukuxhuma uthi lwe-FM. Ukuze udlulise kangcono amasiginali we-FM, kunconywa ukuthi uxhume uthi lwesiswebhu ubude obungu-75cm, futhi akufanele kube nezithiyo ngangokunokwenzeka eduze nothi.

<3>: Ukulungiswa kwemvamisa

Le mojula idinga ukusebenzisa ikhompuyutha ukulungisa iphoyinti lefrikhwensi yomsakazo (bheka indlela yokumisa imvamisa engxenyeni engezansi yekhasi lemininingwane ukuze uthole indlela ethile yokusebenza).

Izindaba ezidinga ukunakwa:

1: Sicela uqinisekise ukuthi i-polarity yokunikezwa kwamandla kanye ne-voltage yokuphakela amandla kulungile ngaphambi kokuvula amandla. Uma i-voltage yokufaka idlula i-5V noma izigxobo ezinhle nezingezinhle zokunikezwa kwamandla zixhunywa ngokuhlehla, kungase kubangele umonakalo unomphela kumojuli.

2: Ungathinti izingxenye ezingemuva zemojuli lapho usebenza, ukuze ungaphazamisi ukusebenza okuvamile kwemojula.

Lungisa incazelo yokuthatha imakrofoni:

Le mojula ingashintsha ukuzwela kokuthathwa kwemakrofoni ngokulungisa impendulo engemihle yesekethe ye-preamplifier yemakrofoni., ukuze kuhlangatshezwane nokujwayela abasebenzisi abangabodwana kuzimfuneko ezikhethekile zokuzwela. Inani elizenzakalelayo lasekuqaleni lokumelana nempendulo engemihle ye-microphone preamplifier ngu-82K ohms. Ukwandisa lokhu kumelana kukhulisa ukuzwela kombhobho ngenkathi ukwehlisa lokhu kumelana kunciphisa ukuzwela kombhobho.. inothi: Sinikeza kuphela indlela yokuguqula. Uma ufuna ukuyishintsha, sicela uyithenge futhi uzilungise ngokwakho. Konke ukuthunyelwa kusekelwe ekuzweleni okuzenzakalelayo. Asiwashintshi amapharamitha wokuzwela kukhasimende ngalinye.

Indlela yokumisa imvamisa nenqubo:

1: I-USB kuya kumojula ye-TTL kanye nendlela yokuxhumana yemojuli

(2): xhuma i-USB kumojula yembobo ye-serial kanye nemojuli ngemva kokufaka i-USB kumojula ye-serial kukhompyutha, ilinde ukuthi umshayeli azifake ngokuzenzakalela ngemva kokuphela kokufaka vula ngokuzenzakalelayo imenenja yedivayisi ukuze ubone i-USB kuya kumojula ye-TTL ehambisana nenombolo yembobo ye-serial
