Four Pack PCA9685 16 Channel 12 Bit PWM Servo Driver Board For I2C Interface, Plug And Play With Up To 62 Boards On One Bus, 992 PWM Outputs, Easy Two Pin Setup And 3 Pin Groups, Ideal For Robotics And Hobby Projects

Four-Pack 16-Channel I2C PWM Servo Driver Board
✔️ Controls 16 PWM outputs from 2 pins; supports 62 boards on I2C

This four-pack PWM servo driver uses a 16-channel PWM controller on the I2C bus to drive servos and LEDs. You can cascade up to 62 boards on a single I2C line for a total of 992 PWM outputs, making it ideal for robotics and hobby projects. It runs from a 5-10V supply and is 3.3V MCU-friendly, with 220 ohm resistors on every output for LED protection. Its compact footprint is about 62 x 25 x 13 mm (2.4 x 0.98 x 0.51 in), and it groups connections into 3-pin sets to simplify wiring.

✅ 16-channel, 12-bit PWM per output for precise control
✅ I2C interface with 2-pin control and cascade up to 62 boards on a single bus
✅ 5V compatible, safe with 3.3V MCUs and can drive up to 6V outputs
✅ Frequency range 40-1000 Hz, adjustable up to about 1.6 kHz
✅ Size approx 62 x 25 x 13 mm (2.4 x 0.98 x 0.51 in)
✅ 220 ohm output protection resistors for LED driving
✅ Reverse polarity protection on input and output enable feature
✅ 3-pin connector groups allow wiring of 16 servos at once
