SpecPicks Verdict
SpecPicks scored PCA9685 16 Channel PWM Servo Driver Board 12 bit IIC Interface Module using a rating × review-volume × price-fit model applied to published specs and reviews across the single board computers category. HUAREW'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 contain an I2C communication PWM driver with a built in clock, so you do not need to continuously send it signal tying up your microcontroller
- Green power indicator lamp, 3 pin connectors in groups of 4, so you can plug in 16 servos at one time(servo motor plug slightly wider than 0.1 inch)
- Using only two pins, control 16 free-running PWM, so you can wire up to 62 of these on a single I2C bus, a total of 992 outputs
- 12 bit resolution for each output for servos, that means about 4us resolution at 60Hz update rate
- PCA9685 IIC module 5V compliant, you can also control it from a 3.3V microcontroller and still safely drive up to 6V outputs
