The PCA9548A solves this problem by acting as an I2C switch, allowing your microcontroller to communicate with up to 8 independent I2C channels.\u003c\/p\u003e\n\u003cp\u003eBy selecting the desired channel through the I2C bus, the multiplexer connects the main controller to one of the downstream buses. This makes it easy to use multiple identical sensors such as temperature sensors, OLED displays, or ADC modules in the same project without address conflicts.\u003c\/p\u003e\n\u003cp\u003eThe module communicates using the standard I2C interface, making it compatible with popular platforms such as Arduino, ESP32, Raspberry Pi, and other microcontrollers used in robotics, IoT, and STEM education projects.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHighlights:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong data-start=\"988\" data-end=\"1022\"\u003eI2C Address Conflict Solution:\u003c\/strong\u003e Allows multiple devices with the same I2C address to be used in one system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-start=\"1102\" data-end=\"1133\"\u003e8 Independent I2C Channels:\u003c\/strong\u003e Supports up to 8 separate I2C buses selectable via software.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-start=\"1202\" data-end=\"1229\"\u003eStandard I2C Interface:\u003c\/strong\u003e Simple integration with Arduino, ESP, Raspberry Pi, and other controllers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-start=\"1308\" data-end=\"1344\"\u003eMultiple Multiplexers Supported:\u003c\/strong\u003e Up to 8 PCA9548A modules can be used together for expanding I2C networks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-start=\"1426\" data-end=\"1452\"\u003eCompact Module Design:\u003c\/strong\u003e Small PCB board for easy integration in electronics projects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 2.3-5.5V.\u003cbr data-start=\"1573\" data-end=\"1576\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommunication Protocol:\u003c\/strong\u003e I2C.\u003cbr data-start=\"1604\" data-end=\"1607\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiplexer Channels:\u003c\/strong\u003e 8 independent I2C channels.\u003cbr data-start=\"1656\" data-end=\"1659\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDefault I2C Address:\u003c\/strong\u003e 0x70 or 0x77 (configurable via address pins).\u003cbr data-start=\"1717\" data-end=\"1720\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Devices per Bus:\u003c\/strong\u003e Up to 8 channels per module.\u003cbr data-start=\"1773\" data-end=\"1776\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003e~32\u003c\/span\u003e×21×2mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-start=\"1649\" data-end=\"1663\"\u003eInterface:\u003c\/strong\u003e\u003cspan\u003e 24\u003c\/span\u003e\u003cspan\u003e-pin (VIN, GND,\u003c\/span\u003e SDA, SCL, RST, A0-A2, SD0-SD7, SC0-SC7).\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIdeal For:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e🔌 Expanding I2C device connections.\u003cbr data-start=\"1929\" data-end=\"1932\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e📡 Projects using multiple identical I2C sensors.\u003cbr data-start=\"1981\" data-end=\"1984\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e🤖 Robotics and automation systems.\u003cbr data-start=\"2019\" data-end=\"2022\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e🌐 IoT and sensor network projects.\u003cbr data-start=\"2057\" data-end=\"2060\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e🎓 Arduino \u0026amp; STEM education projects.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1842\" data-end=\"1851\"\u003e\u003cstrong data-start=\"1842\" data-end=\"1851\"\u003eNote:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"1853\" data-end=\"1980\"\u003eProduct appearance may vary slightly from the images shown.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1853\" data-end=\"1980\"\u003eText or markings on the module may differ depending on the batch.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBO CY","offers":[{"title":"Default Title","offer_id":56521053634884,"sku":null,"price":5.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0043\/7154\/6227\/files\/PCA9548A-1.png?v=1774590293","url":"https:\/\/robo.com.cy\/en-in\/products\/multiplexer-for-i2c-pca9548a","provider":"ROBO CY","version":"1.0","type":"link"}
