High-concerned chemical : none Type : Module Brand Name : diymore Origin : Mainland China Condition : New

Features: 1. It has LED terminal output pins and can be operated by code using 16 PWM channels. 2. Supports 12 bit PWM resolution, with more precise brightness adjustment. 3. Programmable frequency, suitable for various scene requirements. 4. Support external clock input to achieve synchronous control of multiple devices. 5. The working voltage is 2.3V-5.5V, with strong compatibility, and the LED can be directly connected to the LED output. Product Introduction: PCA9685 is a 16 channel LED controller that supports I2C interface, designed specifically for RGBA backlight applications. It has 12 bit resolution (4096 levels) independent PWM control, adjustable frequency range of 24Hz-1526Hz, and supports currents up to 25mA. Its unique features include interleaved switching time, external clock synchronization, and finer brightness adjustment, making it ideal for LCD backlight and ambient lighting applications. PCA9685 is a 16 channel LED controller controlled by I2C bus, specifically designed for red/green/blue/amber (RGBA) backlight applications. Each LED output has its own 12 bit resolution (4096 steps) fixed frequency independent PWM controller At a typical programmable frequency of 24Hz to 1526Hz, the duty cycle can be adjusted from 0% to 100% to allow the LED to be set to a specific brightness value. All outputs are set to the same PWM frequency. Each LED output can be turned off or on (without PWM control), or its value can be set on its separate PWM controller. The LED output driver is programmed to have a drain open circuit absorption capacity of 25mA at 5V or a totem pole with 25mA absorption, and a 10mA power supply capacity at 5V. The power supply voltage range of PCA9685 is 2.3 V to 5.5 V, with input and output voltages of 5.5V. The LED can be directly connected to the LED output (up to 25mA, 5.5V) or controlled by an external driver and minimum discrete quantity for larger current or higher voltage LED components. Parameter: The working power supply voltage range is 2.3V to 5.5V A typical internal oscillator at 25 MHz does not require external components External 50 MHz (maximum) clock input Internal power on reset Low standby current IIC interface, same port on both sides. Can be used for driving scheme verification. Equipped with LED terminal lead out pins, capable of code operation using 16 PWM channels. The IIC address can be modified through solder pads.
