{"title":"Adafruit 16-Channel PWM / Servo Bonnet for Raspberry Pi","handle":"adafruit-16-channel-pwm-servo-bonnet-for-raspberry-pi","url":"/products/adafruit-16-channel-pwm-servo-bonnet-for-raspberry-pi","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.\n\nUp 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.\n\nKey Features\n\n\n16 PWM Channels – 12-bit resolution (4,096 steps) per output\n\nPCA9685 Driver – Free-running I2C-controlled PWM with built-in clock\n\nStackable – Up to 62 bonnets on one I2C bus (992 total outputs)\n\n3.3V/5V Logic – Default 3.3V output with solder jumper for 5V\n\nAdjustable Frequency – PWM up to ~1.6 kHz\n\nServo Connectors – 3-pin headers in groups of 4 for up to 16 servos\n\nPython Library – Ready-to-use library for quick setup\n\n\nAlso Available\n\n\n16-Channel PWM/Servo HAT for Raspberry Pi – HAT format mini kit\n\n16-Channel PWM/Servo Driver Breakout – Breadboard-friendly breakout\n\n\nCompatibility\n\nRaspberry Pi Zero / Zero W\nRaspberry Pi A+ / B+\nRaspberry Pi 2 / 3 / 3B+ / 4\nAny Pi with 2×20 GPIO header\n\n\nPackage Contents\n\n1× Adafruit 16-Channel PWM/Servo Bonnet\n1× 2-pin terminal block\n1× 2.1mm DC jack\n4× 3×4 male headers\n\n\n\nImportant: 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.\n\n\nSpecifications\n\n\nDriver Chip – PCA9685\n\nChannels – 16\n\nPWM Resolution – 12-bit (4,096 steps)\n\nMax PWM Frequency – ~1.6 kHz\n\nInterface – I2C\n\nForm Factor – Raspberry Pi Bonnet (2×20 header)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6392,"title":"Default Title","sku":"AF-3416","price":26.83,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":73,"option1":"Default Title"}]}
