TECNOULAB 5pcs PCA9685 16 Channel 12bit PWM servo controller interface I2C

【PCA9685】 PCA9685 Interface I2C PWM Servo Driver 16bit and 12bit for Arduino Raspberry Pi DIY Servo Shield Module 【Easy Operation】 It is an i2c controlled PWM controller with a built-in clock. That means that, unlike the TLC5940 family, you don't need to continuously send the connection signal to your microcontroller, it's completely free! 【Compact Design】 It is 5V compatible, which means you can control it from a 3.3V microcontroller and safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with more than 3.4 voltages forward) 【COMPATABILITY】 - 6 direction selection pins so you can connect up to 62 of them on a single i2c bus, a total of 992 outputs, which are many servos or LEDs.Output enable pin to quickly disable all outputs. 【COMPATABILITY】PWM frequency adjustable up to about 1.6KHz, 12-bit resolution for each output: for servos, that means approximately 4us resolution at 60Hz. Refresh speed. Configurable push-pull or open drain outlet.
