16 Channel 12-bit PWM Servo motor Driver I2C Module

Description

The PCA9685 16-Channel 12-Bit PWM Servo Driver is an \(I^{2}C\) breakout board that allows you to control up to \(16\) servo motors or dim LEDs using only \(2\) microcontroller pins. It features a built-in clock, freeing up your main board from continuously generating timing signals. [1, 2, 3]

Key Highlights

• High Capacity: Controls \(16\) free-running PWM outputs. Daisy-chain up to \(62\) modules for a total of \(992\) channels.
• High Precision: \(12\)-bit resolution delivers \(4096\) steps of adjustability, enabling smooth servo positioning.
• Independent Power: Equipped with a screw terminal block to supply external power, preventing strain on your microcontroller.
• Broad Compatibility: Fully 5V compliant and 3.3V logic compatible, making it ideal for Arduino, Raspberry Pi, and other microcontrollers.
