Product Description
The PCA9685 16-Channel Servo Driver is a powerful $I^2C$-controlled PWM expansion module that allows you to drive up to 16 servo motors using only two pins from your microcontroller. This "Soldered" version comes ready-to-use with all header pins pre-installed, saving you time and effort in your Pimpri workshop. Each of the 16 outputs has a 12-bit resolution, providing 4096 steps of precision for ultra-smooth servo positioning. At Robogears, we recommend this module for complex robotics projects like hexapods, robotic arms, and animatronics, where the built-in clock ensures that once a position is set, the microcontroller is free to perform other tasks without having to continuously send pulses.
Detailed Key Features
$I^2C$ Control Efficiency: Uses only two pins (SDA/SCL) to control 16 servos, leaving the rest of your Arduino or ESP32 pins free for sensors and peripherals.
Chainable Design: Features address-select jumpers, allowing you to chain up to 62 drivers on a single $I^2C$ bus to control a staggering 992 servos.
Dedicated Power Input: Includes a terminal block for external power input, ensuring that the high current draw of multiple servos doesn't damage your microcontroller.
12-bit PWM Precision: Delivers a 4096-step resolution for extremely fine control over servo angles and LED brightness.
Pre-Soldered Convenience: Arrives with all male headers and terminal blocks pre-soldered, making it perfect for rapid prototyping and educational environments.
