Product Details
PCA9685 16-Channel 12-Bit PWM Servo Driver (I2C Interface for Arduino & Raspberry Pi)
The PCA9685 16-channel 12-bit PWM servo driver module is a high-performance breakout board that allows precise control of up to 16 servos or LEDs using an I²C interface. Built around NXP's PCA9685 chip, it supports 12-bit (4096-step) resolution for each channel and is compatible with Arduino, ESP32, and Raspberry Pi platforms.
It includes a built-in 25 MHz oscillator and a power input for external 5 V servo supplies, making it ideal for robotics, drones, lighting control, and automation applications.
🔧 Key Features
- 16-channel, 12-bit PWM resolution for precise control.
- Up to 62 boards can be chained via I²C addressing.
- Operates from 2.3 V to 5.5 V (logic level).
- Drives servos or LEDs with external power support (V+ up to 6 V).
- Fully compatible with Arduino, Raspberry Pi, and ESP boards.
- Default I²C address: 0x40 (configurable).
