Build the robot of your dreams, not a wiring nightmare. Microcontrollers like the Arduino have a limit on PWM pins—but the PCA9685 Driver breaks that barrier. This smart I2C controller allows you to drive 16 individual servos or LEDs using only two data pins on your board. Whether you are building a complex hexapod walker, a multi-jointed robotic arm, or a massive lighting array, this module handles the heavy lifting, keeping your main processor free for other tasks.
- CONTROL 16 SERVOS: Instantly expand your system to drive up to 16 separate PWM channels simultaneously, perfect for complex mechanical projects that standard boards can't handle.
- 12-BIT PRECISION: Delivers high-resolution control (4096 steps per channel), ensuring buttery smooth servo movement and flicker-free dimming for LED strips.
- 2-PIN I2C INTERFACE: Communicates via the standard I2C bus (SDA/SCL), meaning you can control dozens of motors without using up your microcontroller's valuable digital I/O pins.
- EXTERNAL POWER TERMINAL: Features a dedicated screw terminal and protection capacitor to safely supply high-current power (up to 6V) directly to the motors, bypassing the delicate logic board.
- CHAINABLE DESIGN: Need more? The addressable design allows you to daisy-chain up to 62 modules together, giving you control over a staggering 992 PWM outputs from a single controller.
- 3.3V & 5V LOGIC: Fully 5V compliant, allowing you to control it safely with a 3.3V Raspberry Pi while still driving standard high-power 5V servos.
