Pros & Cons
Pros
- ✓ Backed by HUAREW's warranty and support channels
- ✓ Ships via Amazon with Prime eligibility and the standard returns policy
Cons
- ✗ Confirm socket / form-factor / power-rating compatibility against your build before ordering
- ✗ Price, stock, and Prime eligibility update from Amazon and may have changed since this page was last verified
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
