Servo Driver HAT (B) for Raspberry Pi 16-Channel with I2C
This HAT from Waveshare generates up to 16 PWM signals for servos with the PCA9685 and is controlled via I2C using only two pins. It fits the 40-pin header of the Raspberry Pi and also works with the Jetson Nano. On version (B) the servo connectors are angled pin headers pointing sideways away from the board. A built-in 5 V regulator with up to 3 A supplies the servos, either from the Raspberry Pi or via the VIN screw terminal with 6 to 12 V.
Important: Ex works, the servos are powered from the 5 V of the Raspberry Pi. With powerful servos such as the MG996R this voltage drops and the Raspberry Pi restarts. In that case, according to Waveshare, remove the 0 Ω resistor on the board and supply the servos via VIN with 6 to 12 V.
