Have you ever felt anxious because of the limited number of development board PWM output interfaces? Don't worry! The Grove - 16-Channel PWM Driver is based on NXP PCA9685, which is a 16-Channel 12bit I2C PWM driver. This PCA9685 16-Channel 12bit I2C PWM driver board can drive up to 16 servos with external power supply.
Based on the features of NXP PCA9685, this PWM driver board can well meet the needs of multi-channel PWM projects, such as a hexapod walker, MarsCar. Additionally, you can use this board as a LED controller. You can easily control this driver board through the I2C Grove interface.
We've Released the Grove Selection Guide and hope to help you find the Grove suit you best.
6 hardware address pins allow 62 PCA9685 devices to be connected to the same I2C-bus
Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. Not only are these open hardware, but we also have open-source software.
We prepared this blog How to use Grove – 16-Channel PWM Driver (PCA9685) to Control Robotic Arm to help you get started with the drive and learn more about PWM driver and PCA9685.
