Manufacturer description

Features:It's an I2C-controlled 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 microcontroller, its completely free running! Output enable pin to quickly disable all the outputs.-The PCA9685 chip is wrapped in the center of the board-16-way steering gear control-Power input terminal-Green power indicator-Using I2C communication, built in PWM driver and a clock.-Compatible with 5V,can also use 3.3V MCU control and safely drive to 6V output.-Address selects pins, so you can put 62 driver board hanging…

SpecPicks Verdict

SpecPicks scored 3PCS PCA9685 16 CH Channel PWM Servo Motor Driver Board Controller… using a rating × review-volume × price-fit model applied to published specs and reviews across the single board computers category. VKLSVAN's single board computers lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for single board computers of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Key Features

  • PCA9685 Contains an I2C-controlled PWM driver with a built-in clock; Power supply voltage is DC5-10V
  • It is 5V compliant, 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).
  • Supports using only two pins to control 16 free-running PWM outputs ¨C you can even chain up 62 breakouts to control up to 992 PWM outputs.
  • 3 pin connectors in groups of 4, so you can plug in 16 servos at one time .
  • 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
