The module also has outputs that will either drive an 8ohm speaker connected to the SPK+ and SPK- pins, or drive a single ended amplifier directly from its DAC output via the AUDIO-L pin. There are also several options for controlling playback including interfacing push buttons for play\/pause, track forward\/backwards and volume up\/down. Alternatively the module can be controlled via a two wire serial interface (clock and data) that allows for random track selection and playback control.\u003c\/p\u003e\n\u003cp\u003ePlease note: The digital pins are not 5V tolerant. If interfacing to a 5V microcontroller, the datasheet recommends using 470R resistors between the microcontroller and this module. Alternatively a level shifter or potential divider can be used. MP3 format files will need to be converted to AD4 format for playback.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cul\u003e\n\u003cli\u003eA634Products for WTV020 chip module plug the SD card, supports 2.32M ~ 1GBit capacity card;\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003eSupports the FAT file system, SD card as storage medium;\u003c\/li\u003e\n\u003cli\u003eAnd supports playback of WAV format files 4Bit ADCPM;\u003c\/li\u003e\n\u003cli\u003eSupports automatic speech recognition folders and file playback;\u003c\/li\u003e\n\u003cli\u003eYou can play background music and commercials language;\u003c\/li\u003e\n\u003cli\u003eControl methods are key control, two-line control and UART232 serial control;\u003c\/li\u003e\n\u003cli\u003eWTV master chip has WTV020-16SOP and WTV020-20SOP two packages, both of which are compatible;\u003c\/li\u003e\n\u003cli\u003eYou can play any segment of speech;\u003c\/li\u003e\n\u003cli\u003eOperating voltage: DC2.6 ~ 3.6V;\u003c\/li\u003e\n\u003cli\u003eClassified by folder store content, easy to operate.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eSupports FAT file system SD carrier\u003c\/li\u003e\n\u003cli\u003eSupports playing of 4Bit ADCPM format files\u003c\/li\u003e\n\u003cli\u003eRecognize the voice files automatically\u003c\/li\u003e\n\u003cli\u003eSupport micro-processor and key control\u003c\/li\u003e\n\u003cli\u003eCould be called any paragraph voice playing\u003c\/li\u003e\n\u003cli\u003eSaving operation data when power off\u003c\/li\u003e\n\u003cli\u003eLoading voice to the SD card without assistance of software\u003c\/li\u003e\n\u003cli\u003eSupport combination playing of file (including mute combination)\u003c\/li\u003e\n\u003cli\u003eMemory contents classified by file\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePackage Include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 x WTV020-SD-16P Module\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eModel : WTVO20\u003c\/li\u003e\n\u003cli\u003eDuration : 20 s\u003c\/li\u003e\n\u003cli\u003eTrack : Mono\u003c\/li\u003e\n\u003cli\u003eAudio Output : DAC\/PWM\u003c\/li\u003e\n\u003cli\u003eKey Board Trigger I\/O : 7\u003c\/li\u003e\n\u003cli\u003eParallet Address : 7\u003c\/li\u003e\n\u003cli\u003eControl Modes : Keyboard Prallel(COM+SBT)\/ Serial\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003ch2\u003eDownloads\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"http:\/\/archive.communica.co.za\/Content\/Catalog\/Documents\/D2290179173.pdf\"\u003eDatasheet - WTV020\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/div\u003e\n\u003ch2\u003eAdditional Information\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003ctable border=\"1\" cellpadding=\"7\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDevice\u003c\/td\u003e\n\u003ctd\u003eSound Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eWTV020 | Mini | SD Card | MP3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Communica","offers":[{"title":"Default Title","offer_id":44756868202540,"sku":"BMT WTV020 MINI SD CARD MP3 MODU","price":65.22,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/5376\/1068\/files\/bmt-wtv020-mini-sd-card-mp3-modu-439943.jpg?v=1757346936","url":"https:\/\/xytron.ae\/products\/bmt-wtv020-mini-sd-card-mp3-modu","provider":"Xytron","version":"1.0","type":"link"}
