## Description

The Adafruit 16-Channel PWM/Servo Bonnet adds precision servo and PWM control to your Raspberry Pi. Using the PCA9685 I2C PWM controller, it drives up to 16 servos or PWM outputs simultaneously with 12-bit resolution — completely free-running with no Pi processing overhead. Up to 62 bonnets can be stacked on a single I2C bus for control of up to 992 servos. The board works with any servo that accepts 5V power and 3.3V logic signals, with an optional solder jumper to switch output logic to 5V. Key Features 16 PWM Channels – 12-bit resolution (4,096 steps) per output PCA9685 Driver – Free-running I2C-controlled PWM with built-in clock Stackable – Up to 62 bonnets on one I2C bus (992 total outputs) 3.3V/5V Logic – Default 3.3V output with solder jumper for 5V Adjustable Frequency – PWM up to ~1.6 kHz Servo Connectors – 3-pin headers in groups of 4 for up to 16 servos Python Library – Ready-to-use library for quick setup Also Available 16-Channel PWM/Servo HAT for Raspberry Pi – HAT format mini kit 16-Channel PWM/Servo Driver Breakout – Breadboard-friendly breakout Compatibility Raspberry Pi Zero / Zero W Raspberry Pi A+ / B+ Raspberry Pi 2 / 3 / 3B+ / 4 Any Pi with 2×20 GPIO header Package Contents 1× Adafruit 16-Channel PWM/Servo Bonnet 1× 2-pin terminal block 1× 2.1mm DC jack 4× 3×4 male headers Important: Raspberry Pi, servos, and 5V power supply not included. A separate 5–6V power supply is required for the servos. Not compatible with original Pi Model A/B (2×13 header). Terminal block colour may vary. Specifications Driver Chip – PCA9685 Channels – 16 PWM Resolution – 12-bit (4,096 steps) Max PWM Frequency – ~1.6 kHz Interface – I2C Form Factor – Raspberry Pi Bonnet (2×20 header)
