Through this ADC module, Raspberry Pi can easily use a wide range of Gravity series analog sensors to measure various signals, and perceive this world.\u003cbr\u003e\u003cbr\u003e Raspberry Pi is a common master control board which is powerful in its functions, but the I\/O pins of Raspberry Pi can read digital signals only, what's more, only through an external analog-to-digital conversion (ADC) module can it read signals of analog sensor or device, it is not convenient to use.\u003cbr\u003e\u003cbr\u003e DFRobot I2C ADS1115 16-bit ADC module is specially designed for Raspberry Pi and Gravity series analog sensors, which greatly reduces the difficulty of using the Gravity series analog sensors, plug and play, no welding, very convenient. The number of Gravity series sensors is large and its wide variety can meet the needs of various sensors of the Raspberry Pi.\u003cbr\u003e\u003cbr\u003e This module uses 16-bit ADC chip ADS1115, supports 3.3 ~ 5V wide voltage power supply. The chip has a precision reference voltage and programmable gain adjustment (PGA), therefore, accurate acquisition and conversion can be performed for both weak and highly variable signals. So it is also applicable to all types of applications that the main control board needs to accurately collect the analog signals.\u003cbr\u003e\u003cbr\u003e One ADC module can read analog signals of 4 channels. Because of the on-board I2C address selection switch, it supports the cascade of two ADC modules and can read analog signals of 8 channels, it can satisfy the needs of various applications.\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cstrong\u003eNote: The voltage on analog input pins must be less than VCC+0.3V!\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"desCon\"\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eSupport 3.3~5.0V Wide Supply Voltage\u003c\/li\u003e\n\u003cli\u003e3.3V I2C digital level signal, optimized for Raspberry Pi\u003c\/li\u003e\n\u003cli\u003eGravity I2C Interface, plug and play\u003c\/li\u003e\n\u003cli\u003eOn-board I2C address selection switch, supports cascade of two ADC modules\u003c\/li\u003e\n\u003cli\u003eColour-coded 3pin headers, plug and play with Gravity analog sensors\u003c\/li\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"desCon\"\u003e\u003c\/div\u003e\n\u003ch2 class=\"desCon\"\u003eConnection Example - Raspberry Pi 3B\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/I2C_ADS1115_16-Bit_ADC_Module_features_1.jpg?v=1692878828\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eSupply Voltage (VCC): 3.3~5.0V\u003c\/li\u003e\n\u003cli\u003eAnalog Signal Detection Range: 0~VCC\u003c\/li\u003e\n\u003cli\u003eNumber of Analog Channels: 4\u003c\/li\u003e\n\u003cli\u003eADC Bits: 16 Bit\u003c\/li\u003e\n\u003cli\u003eOperating Current: 2~3mA (Not include sensor module)\u003c\/li\u003e\n\u003cli\u003eInterface Type: Gravity I2C\u003c\/li\u003e\n\u003cli\u003eInterface Level: High 3.3V, Low 0V\u003c\/li\u003e\n\u003cli\u003eProduct Size: 32mm x 32mm\u003c\/li\u003e\n\u003c\/div\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003eProduct Wiki\u003c\/li\u003e\n\u003cli\u003eMore Documents\u003c\/li\u003e\n\u003c\/div\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cli\u003e1x Gravity: I2C ADS1115 16-bit ADC Module\u003c\/li\u003e\n\u003cli\u003e1x XH2.54-4pin Header\u003c\/li\u003e\n\u003cli\u003e1x Gravity-4P I2C\/ UART Sensor Wire\u003c\/li\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":43493252399181,"sku":"yeg1787258169692","price":8.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/gravity-i2c-ads1115-16-bit-adc-module_1.jpg?v=1787258174","url":"https:\/\/www.grandorchard.shop\/products\/gravity-i2c-ads1115-16-bit-adc-module","provider":"My Store","version":"1.0","type":"link"}
