PCA9685 Compatible 16 Channel PWM Servo Driver With I2C Interface For Arduino And Raspberry Pi 12Bit PWM Controller With Built In Clock Free Running 5V Compliant And Safe For 3V3 Logic

16-Channel PWM Servo Driver with I2C Clock - single or 2-pack
✔️ 2-pin control for 16 free-running PWM outputs with I2C clock

This compact board provides 16 independent PWM outputs controlled via I2C. It's ideal for hobby robotics, CNC projects, and LED driving where a host MCU can offload PWM timing while remaining 3.3V logic compatible.

✅ 12-bit resolution per channel for precise servo positioning
✅ Free-running I2C PWM driver with built-in clock to avoid constant signaling
✅ 5V tolerant and safe for 3.3V logic, outputs up to 6V
✅ 16 channels from a 2-pin interface; stack up to 62 boards for 992 outputs
✅ 4us timing resolution per servo at 60 Hz update

💡 What is a PWM servo driver used for in hobby robotics?

These devices offload PWM timing from your MCU, letting you control many motors with precise timing.

- multi-channel PWM control for robotics and automation - reduces CPU load while keeping precise PWM timing - compatible with Arduino and Raspberry Pi via I2C interface - stackable boards expand output capacity for larger projects
