PCA9685 is a high-performance 16-channel 12-bit PWM servo driver board designed for robotics and DIY projects. It uses the I2C (IIC) interface to communicate with microcontrollers, saving valuable GPIO pins while enabling control of up to 16 servos or PWM devices at once.
With 12-bit resolution (4096 steps), it provides ultra-smooth and precise positioning for servos, ideal for robotic arms, hexapods, and humanoid robots. The adjustable PWM frequency (24Hz1.6kHz) supports both standard servos (50Hz) and LED dimming applications
The board features a compact design with terminal blocks for easy power and servo connections. It includes an onboard 5V regulator, reverse polarity protection, and an output enable pin for safe operation. Multiple modules can be cascaded on a single I2C bus for large-scale projects.
