16-Channel PWM Driver is based on NXP PCA9685, which is a 16-Channel, 12 bit I2C PWM driver. This board can drive up to 16 servos with the external power supply. You can control this board with Arduino easily via the I2C Grove interface. In addition, you can use this board as a LED controller.
Feature¶
- 1 MHz Fast-mode Plus compatible I2C-bus
- 6 hardware address pins allow 62 PCA9685 devices to be connected to the same I2C-bus
- Low standby current
- Noise filter on SDA/SCL inputs
