It uses the AD9833 programmable waveform generator + STM32F0 control scheme. It provides an I2C communication interface (addr: 0x31) and operates by configuring registers in practical use. It allows easy control of the signal source to output various waveforms (sine wave, triangle wave, square wave output, sawtooth wave, signal output amplitude 0-0.6V), and to adjust frequency and phase. It also supports sleep strategies to further reduce power consumption when idle. This Unit is suitable for use as a signal source in the electronic circuit prototyping of various test instruments.\u003c\/p\u003e\n\u003ch2 id=\"features\" data-id=\"Features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDigitally programmable frequency and phase\u003c\/li\u003e\n\u003cli\u003eSignal output amplitude 0-0.6V\u003c\/li\u003e\n\u003cli\u003eSine wave\/triangle wave\/square wave\/sawtooth wave (fixed frequency: 13.6KHz)\/DC output\u003c\/li\u003e\n\u003cli\u003eOutput frequency range: 0MHz to 1MHz (10MHz reference clock)\u003c\/li\u003e\n\u003cli\u003e28-bit frequency resolution\u003c\/li\u003e\n\u003cli\u003e11-bit phase resolution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"includes\" data-id=\"Includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Unit DDS\u003c\/li\u003e\n\u003cli\u003e1 x HY2.0-4P Grove cable (20cm)\u003c\/li\u003e\n\u003cli\u003e1 x SMA-2.54mm cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"applications\" data-id=\"Applications\"\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFrequency stimulation\/waveform generation\u003c\/li\u003e\n\u003cli\u003eLiquid and gas flow measurement\u003c\/li\u003e\n\u003cli\u003eSensor applications: proximity, motion, and defect detection\u003c\/li\u003e\n\u003cli\u003eLine loss\/attenuation\u003c\/li\u003e\n\u003cli\u003eTesting and medical equipment\u003c\/li\u003e\n\u003cli\u003eSweep\/clock generator\u003c\/li\u003e\n\u003cli\u003eTime-domain reflection (TDR) applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"specifications\" data-id=\"Specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMCU\u003c\/td\u003e\n\u003ctd\u003eSTM32F031G4U6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eI2C @0x31\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Waveforms\u003c\/td\u003e\n\u003ctd\u003eSine wave\/triangle wave\/square wave\/sawtooth wave (fixed frequency: 13.6KHz)\/DC output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Output Amplitude\u003c\/td\u003e\n\u003ctd\u003e0-0.6V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Frequency Range\u003c\/td\u003e\n\u003ctd\u003e0 MHz to 1MHz (10 MHz reference clock)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Resolution\u003c\/td\u003e\n\u003ctd\u003e28-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Resolution\u003c\/td\u003e\n\u003ctd\u003e11-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e71.4 x 24.0 x 8.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e11.2g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e88.0 x 60.0 x 21.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e34.0g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLearn and Documents\u003c\/h2\u003e\n → DOCUMENTS \n\u003c\/div\u003e","brand":"m5stack-store","offers":[{"title":"Default Title","offer_id":53634552496421,"sku":"mkd1787247082263","price":20.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0936\/6251\/1397\/files\/dds-unit-ad9833_1.jpg?v=1787247090","url":"https:\/\/hypestepstore.shop\/products\/dds-unit-ad9833","provider":"My Store","version":"1.0","type":"link"}
