16-Channel PWM Servo Controller Shield for Arduino

16-Channel PWM Servo Controller Shield for Arduino

A 16-channel PWM servo controller shield based on the PCA9685 I2C PWM driver. Stacks directly onto Arduino Uno or Mega and allows control of up to 16 servos or PWM devices simultaneously via just 2 I2C wires — freeing up all Arduino digital pins for other uses. Features 12-bit resolution and adjustable PWM frequency from 40Hz to 1000Hz.

Key Specifications

• Driver: PCA9685 | Channels: 16 PWM outputs
• Interface: I2C | Address: 0x40 (configurable)
• Resolution: 12-bit (4096 steps) | Frequency: 40–1000Hz
• Servo power: Separate VCC input (up to 6V for servos)
• Compatible: Arduino Uno / Mega / Leonardo
• Compliance: RoHS compliant

Why Choose This?

• ✅ 16 servos via 2 I2C wires — frees all Arduino digital pins for other uses
• ✅ Chainable — stack multiple shields for up to 992 PWM channels
• ✅ 12-bit resolution — smooth, precise servo positioning
• ✅ Separate servo power — power servos independently from Arduino logic

Typical Applications

• Robotic arm and hexapod robot servo control
• Pan-tilt camera gimbal control
• LED PWM dimming and RGB control
• Multi-servo animatronics and puppetry
