This is a PWM/servo expansion board Compatible with Raspberry Pi 5/4/3B+/3B/Zero/Zero W/Zero WH/ Zero 2W and Jetson Nano. It can expand 16-ch servo control or PWM output through the PCA9685 chip, and each channel has a 12-bit resolution. With the I2C interface for controlling, it does not require any other pins. ^^ I2C interface control, only 2 signal lines are needed to achieve servo drive. Reserved I2C control interface for easy access to other main control boards. ^^ Supports up to 16 servos or PWM outputs, each with 12-bit resolution (4096 levels).
It is suitable for controlling robotic arms and various servo robots. ^^ Onboard 5V voltage regulator chip, output up to 3A current, can be connected to battery power through VIN terminal. ^^ Onboard standard servo interface, can be connected to SG90, MG90S, MG996R and other common servos. ^^ Comes with Online Development Resources /User Manual, please
