The PCA9685 is a 16-channel I2C-bus controlled LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has individual 12-bit resolution (4096 steps) PWM controller with a fixed frequency. The controller operates at a programmable frequency from a typical 24 Hz to 1526 Hz with a duty cycle that is adjustable from 0% to 100% so the LED can be set to output a specific brightness. All outputs are set to the same PWM frequency. With the PCA9685 as the master chip, the 16-channel 12-bit PWM Servo Driver only needs 2 pins to control 16 servos, thus greatly reducing the occupant I/Os. Moreover, it can be connected to 62 driver boards at most in a cascade way, which means it will be able to control 992 servos in total.
Features:
Contains an I2C-controlled PWM driver with a built-in clock. It means, unlike the TLC5940 family, you do not need to continuously send it signals tying up your microcontroller; it's completely free running!
5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs, which is good when you want to control white or blue LEDs with a 3.4V+ forward voltage
Supports using only two pins to control 16 free-running PWM outputs – you can even chain up 62 breakouts to control up to 992 PWM outputs.
3 pin connectors in 4 groups, so you can plug in 16 servos at one time (Servo plugs are slightly wider than 0.1" so you can only stack 4 adjacent ones on 0.1"-hole female headers.
12-bit resolution for each output - for servos, that means about 4us resolution at an update rate of 60Hz.

Careful, careful, no return policy once ordered, Monitor is very fragile
I order 15.6 inch monitor with built in stand for my Raspberry PI. The issue with built in stand, is that it is so fragile that a slight movement in cables the monitor will move and it can topple breaking the LCD panel. The stand does not help monitor to be in one place, not suitable for regular use.
Be careful before ordering this product as as the company does not accept returns and has not return policy, be careful careful careful.
This is Delhi based company which is importing items from China and selling without any return policy.
