{"product_id":"pca9685","title":"PCA9685","description":"\u003cp\u003eThe PCA9685 is a 16-channel, 12-bit PWM\/Servo Driver controlled via I2C using just 2 pins. Completely free-running — no need to continuously send signals from the MCU. 5V-tolerant, so it can be driven from a 3.3V microcontroller while safely powering up to 6V outputs (useful for high-forward-voltage LEDs and servos). Chain up to 62 boards on a single I2C bus for up to 992 PWM outputs.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eChannels: 16\u003c\/li\u003e\n\u003cli\u003eResolution: 12-bit per channel\u003c\/li\u003e\n\u003cli\u003ePWM Frequency: Adjustable up to ~1.6kHz\u003c\/li\u003e\n\u003cli\u003eInterface: I2C\u003c\/li\u003e\n\u003cli\u003eI2C Address: 0x60–0x80 (6 address select pins)\u003c\/li\u003e\n\u003cli\u003eLogic Voltage: 3.3V or 5V MCU compatible\u003c\/li\u003e\n\u003cli\u003eOutput Voltage: Up to 6V\u003c\/li\u003e\n\u003cli\u003eOutput Mode: Configurable push-pull or open-drain\u003c\/li\u003e\n\u003cli\u003eOutput Enable Pin: Yes (disables all outputs instantly)\u003c\/li\u003e\n\u003cli\u003eReverse polarity protection on terminal block\u003c\/li\u003e\n\u003cli\u003e220Ω series resistors on all output lines\u003c\/li\u003e\n\u003cli\u003eGreen power-good LED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMulti-servo control for robotics and gimbal systems\u003c\/li\u003e\n\u003cli\u003eLED dimming and RGB lighting control\u003c\/li\u003e\n\u003cli\u003eExpanding PWM outputs beyond MCU limits\u003c\/li\u003e\n\u003cli\u003eFlight controller servo and ESC signal distribution\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Powered by INFINITY WORKS","offers":[{"title":"Default Title","offer_id":47371692834870,"sku":"TW288","price":285.6,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9335\/5062\/files\/PCA9685.jpg?v=1787646111","url":"https:\/\/tecwizdom.com\/products\/pca9685","provider":"Tecwizdom.com","version":"1.0","type":"link"}
