16 Channel Servo Motor Driver PCA9685 12 Bit PWM I2C Module For Arduino

With this PCA9685 Servo Motor Driver 16-Channel 12 Bit PWM Servo Motor Driver Module, 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. It’s an I2C-controlled PWM driver with a built-in clock. That means you do not need to continuously send it to signal to tie up your microcontroller, it is completely free running! 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. Our microcontroller has a limited number of PWM outputs, and you find yourself running out! Not with the 16-Channel 12-bit PWM-Servo Driver – I2C interface. With this PWM and servo driver breakout, you can control 16 free-running PWM outputs with just two pins! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these modules for up to an outstanding 992 PWM outputs.

Features:

• Power input via terminal block or 0.1″ spaced pins
• The terminal block has reverse-polarity power input protection
• Green power LED
• Easy chaining of boards
• Power filtration capacitor installation pads
• Configurable as a push-pull or open-drain output
• Output enable pin available for outside-the-microcontroller “shut it down!” control.
• Solder pad jumpers for address selection

Specifications:

• Color: Blue
• 5V compliant, and still talks to a 3.3V microcontroller
• 6 “address select” pins for configuring up to 62 ICs on a single I2C bus
• 3-pin connectors in groups of four for easy 16-servo installations
• PWM frequency adjustable up to approximately 1.6kHz
• 12-bit frequency resolution (equates to about 4µs resolution at 60Hz refresh rate)
• Output line projection resistors: 220Ohm
• Dimension: 62 x 25 x 13mm
