BMT 16CH 12BIT PWM/SERVO DRIVER

SKU: BMT 16CH 12BIT PWM/SERVO DRIVER

BRAND: Communica


16-Channel 12-BIT PWM Servo Control/ Driver - I2C Interface - PCA9685

Overview

Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakout board to control up to 992 PWM outputs (which we would really like to see since it would be glorious)

Features

  • IIC interface, PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your MCU, its completely free running!
  • Power supply 5V, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)
  • Chain able design, 6 address select pins, so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs – that’s a lot of servos or LEDs
  • Adjustable frequency PWM up to about 1.6 KHz
  • 12-bit resolution for each output – for servos, that means about 4us resolution at 60Hz update rate
  • Configurable push-pull or open-drain output
  • Output enable pin to quickly disable all the outputs
  • On board 220ohm resistors can drive for LED output

Specification

  • PCA9685 chip was wrapped in the middle of the small plate
  • Power input terminals
  • Green power light
  • In four groups of 3 pin connector convenient you an insert 16 servo motor, servo motor plug slightly wider than 0.1 “, so you can put 4 to 0.1 “joint)
  • Input reverse polarity protection in a patch panel cascade design
  • V + online placed a large capacitance (in some cases you will need) peripheral input voltage depends on the 10 largest v1000uf capacitance
  • PWM output line put a 220 ohm resistor to protect them, and can be easily drive LEDs
  • Takes 1000UF 10V 105 ° Cap
