Adafruit 16-Channel PWM / Servo Bonnet Raspberry Pi

Adafruit 16-Channel PWM/Servo Bonnet for Raspberry Pi: Precision Control for Robotics and Motion Projects

The Adafruit 16-Channel PWM/Servo Bonnet is a powerful add-on board designed to give your Raspberry Pi seamless and precise control over multiple servo motors and PWM outputs. Using an onboard 12-bit PWM controller, this bonnet eliminates the need for the Pi to generate timing pulses, ensuring smooth and jitter-free servo operation. With just 2 I2C pins, it can drive up to 16 servos or PWM devices simultaneously, and by stacking multiple bonnets, you can control up to 992 servos on a single Raspberry Pi.

Compatible with Raspberry Pi Zero, A+, B+, 2, 3, 4, and 5 (any model with a 2x20 GPIO header), this bonnet supports servo motors powered at 5V with 3.3V logic signals. A solder jumper option allows changing logic levels to 5V for broader compatibility. With a PWM frequency range of up to 1.6 kHz and 12-bit precision, this bonnet is perfect for robotics, animatronics, drones, and any project requiring precise motor or LED control.
