Powered by an internal oscillator, this module produces a fixed-frequency tone the moment voltage is applied — no additional code or signal generation required. Simply connect it to a digital output pin on your Arduino, ESP32, Raspberry Pi, or any 3.3V–5V microcontroller, and drive it HIGH to trigger an audible beep. Its compact PCB-mounted design includes onboard current-limiting components, making it safe and straightforward to integrate into alarm systems, notification circuits, smart home projects, and classroom learning kits.

It operates across the same 3.3V–5V range and interfaces directly with Arduino, ESP32, STM32, and similar platforms. The absence of an internal oscillator means you are in complete control of frequency and duration — ideal for musical projects, custom alert tones, and interactive electronics.

It means it only needs 4 pins for the LCD display: VCC, GND, SDA, SCL. It will saves at least 4 digital \/ analog pins on Arduino. And Gravity interface make it easier to use with our Gravity: IO expansion shield.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(1).jpg\" alt=\"I2C 16x2 Arduino LCD with RGB Backlight Display - Introduction\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(2).jpg\" alt=\"DFR0464 Product Feature\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(3).jpg\" alt=\"DFR0464 Product Feature\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(4).jpg\" alt=\"DFR0464 Application Examples\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(5).jpg\" alt=\"DFR0464 Programming Examples\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(6).jpg\" alt=\"DFR0464 Programming Sample Codes\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(7).jpg\" alt=\"DFR0464 Product Display\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(8).jpg\" alt=\"DFR0464 Product Display\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(9).jpg\" alt=\"DFR0464 Product Display\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0464\/DFR0464%20(10-2).jpg\" alt=\"DFR0464 Product Parameters\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOperating Voltage: 3.3V ~ 5.0V\u003c\/li\u003e\n\u003cli\u003eOperating Current: \u0026lt;60mA\u003c\/li\u003e\n\u003cli\u003eDisplay: 16 * 2\u003c\/li\u003e\n\u003cli\u003eCommunication: I2C\u003c\/li\u003e\n\u003cli\u003eBacklight: RGB adjustable backlight (16 million)\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -20 to + 70 ℃\u003c\/li\u003e\n\u003cli\u003eStorage Temperature: -30 to + 80 ℃\u003c\/li\u003e\n\u003cli\u003eDimension: 87.0 * 32.0 * 13.0mm\/3.42 * 1.26 * 0.51 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eDOCUMENTS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/wiki\/index.php\/Gravity:_I2C_16x2_Arduino_LCD_with_RGB_Backlight_Display_SKU:_DFR0464\" target=\"_blank\"\u003eProduct WIKI\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/wiki\/index.php\/Gravity:_I2C_16x2_Arduino_LCD_with_RGB_Backlight_Display_SKU:_DFR0464#More_Documents\" target=\"_blank\"\u003eMore Documents\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eSHIPPING LIST\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Gravity: I2C 16x2 Arduino LCD with RGB Backlight Display\u003c\/li\u003e\n\u003cli\u003e1x Gravity 4Pin I2C\/UART Sensor Cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":44757223702841,"sku":"DFR0464","price":21.2,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5369\/6313\/products\/dfr0464-_900x600_564x376_5310ed6c-2984-4fae-b30d-ebb723425a6b.jpg?v=1683952277"},{"product_id":"ywrobot-fan-9110-module","title":"Fan 9110 Module","description":"\u003ch2\u003eDESCRIPTION\u003c\/h2\u003e\r\n\u003cp\u003eThis fan module uses N20 strong magnetic motor.

The device records whenever REC is HIGH. This pin must remain HIGH for the duration of the recording. REC takes precedence over either playback (PLAYL or PLAYE) signal. If REC is pulled HIGH during a playback cycle, the playback immediately ceases and recording begins. A record cycle is completed when REC is pulled LOW. An End-of-Message (EOM) marker is internally recorded, enabling a subsequent playback cycle to terminate appropriately. The device automatically powers down to standby mode when REC goes LOW. This pin has an internal pull-down device. Holding this pin HIGH will increase standby current consumption.\u003c\/li\u003e\r\n\u003cli\u003ePLAYE: When a HIGH-going transition is detected on this input pin, a playback cycle begins. Playback continues until an End-of-Message (EOM) marker is encountered or the end of the memory space is reached.
