It lets you safely connect devices operating at different logic levels — for example, a 3.3V sensor to a 5V microcontroller — without a direction pin. Simply apply your reference voltages and enable the translator.\n\nThe PCA9306 supports a low-side voltage range of 1.2–3.3V and a high-side range of 1.8–5.5V. The breakout includes a broken-out enable pin and a second ground pin for convenient wiring.\n\nKey Features\n\n\nDual Bidirectional Translation – Two channels for SDA and SCL (or any two signals)\n\nNo Direction Pin – Automatic bidirectional level shifting\n\nLow Side – 1.2V to 3.3V (VREF1)\n\nHigh Side – 1.8V to 5.5V (VREF2)\n\nI2C & SMBus Compatible – Open-drain bidirectional translation\n\nEnable Pin – Broken out for software control\n\n\nIdeal For\n\nConnecting 3.3V I2C sensors to 5V Arduino boards\nMixed-voltage I2C bus systems\nInterfacing between different logic-level devices\nAny project requiring bidirectional voltage translation\n\n\nPackage Contents\n\n1× SparkFun PCA9306 Level Translator Breakout\n\n\nResources\n\nHookup Guide (SparkFun)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5052,"title":"Default Title","sku":"SF-BOB-15439","price":10.31,"on_sale":false,"in_stock":true,"available_quantity":338,"option1":"Default Title"}]}
