## Description

The Adafruit 16-Channel PWM/Servo Shield brings PCA9685-based servo and PWM control to any Arduino in a convenient shield format. Using only I2C (SCL and SDA), the shield provides 16 channels of 12-bit PWM output with a built-in clock — no continuous signal from your microcontroller needed. Up to 62 shields can be stacked on a single I2C bus for a total of 992 PWM outputs. The shield also features a 5×20 prototyping area for additional wiring, and is 5V compliant for driving outputs up to 6V from a 3.3V Arduino. Key Features 16 PWM Channels – 12-bit resolution (4,096 steps) per output PCA9685 Driver – Free-running I2C-controlled PWM with built-in clock (address 0x40) Stackable – Up to 62 shields on one I2C bus (12 of 16 outputs accessible when stacked) 5V Compliant – Control from 3.3V logic, drive up to 6V outputs Adjustable Frequency – PWM up to ~1.6 kHz Configurable Output – Push-pull or open-drain 220Ω Series Resistors – Output protection and easy LED driving Reverse Polarity Protection – On terminal block power input 5×20 Proto Area – Extra space for custom wiring Servo Connectors – 3-pin headers in groups of 4 for up to 16 servos Also Available 16-Channel PWM/Servo Driver Breakout – Breadboard-friendly breakout format Ideal For Arduino-based robotics with multiple servos Precise LED dimming and colour mixing Kinetic art and animatronics Large-scale PWM output expansion Package Contents 1× Adafruit PCA9685 16-channel PWM/Servo shield (assembled and tested) 4× 3×4 male straight headers (for servo plugs) 1× 2-pin terminal block (for power input) 1× 0.1" header strip Note: Servos and Arduino not included. Light soldering required to attach headers. Terminal block colour may vary (blue or black). Compatible with Arduino UNO, Leonardo, Mega, Zero, Metro M0/M4, and similar R3-format boards. Specifications Driver Chip – PCA9685 Channels – 16 PWM Resolution – 12-bit (4,096 steps) Servo Resolution – ~4µs at 60Hz update rate Max PWM Frequency – ~1.6 kHz Output Voltage – Up to 6V Interface – I2C (6 address select pins) Form Factor – Arduino R3 shield
