16-Channel 12-bit PWM/Servo Driver I2C interface PCA9685 for Arduino Raspberry Pi

Description:-

With this 16 Channel PCA9685 12-Bit PWM/Servo Controller, you can control 16 free-running PWM outputs with just two pins. Want to make a robot or hexapod walker ? Maybe you’re making a piece of art with tons of moving parts, or you need to drive a ton of LEDs with precise PWM output. Your microcontroller has a limited number of PWM outputs, and you find yourself running out! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these beauties for up to an outstanding 992 PWM outputs.

Features:-

• This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers
• Dimensions : 62.5 x 25.4 x 3 mm.
• Weight : 9 gm.
• Terminal block for power input (or you can use the 0.1″ breakouts on the side)
• Reverse polarity protection on the terminal block input
• Green power-good LED
• 3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1″ so you can only stack 4 next to each other on 0.1″ header
• “Chain-able” design
• A spot to place a big capacitor on the V+ line (in case you need it)
• 220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
• Solder jumpers for the 6 address select pins
