PCA9685 16-Channel 12-Bit PWM Servo Driver Module

Drive multiple servos or other PWM-controlled outputs from a controller with limited PWM pins. This PCA9685 module provides 16 channels of 12-bit PWM control through an I2C interface.

More PWM channels for multi-output builds

• ✅ ✅ Expand output capacity — control up to 16 PWM channels from the module.
• ✅ ✅ Keep controller wiring focused — the I2C interface uses two signal pins for communication.
• ✅ ✅ Buy the quantity your project needs — choose a one-, three- or five-module pack.

Use the board in projects with several servos or LED outputs, such as a robot or multi-part prototype. Address selection is provided through board jumpers, allowing modules to be configured for compatible chained setups when the rest of the circuit supports it.

This is an electronics driver module, not a set of servos or LEDs. The product listing describes the board dimensions as approximately 62.5 × 25.4 × 3 mm without headers or terminal block; supplied connectors can vary by board configuration.

Specifications: PCA9685; 16 PWM channels; 12-bit resolution; I2C interface; module size approximately 62.5 × 25.4 × 3 mm excluding headers and terminal block. Pack options: 1, 3 or 5 modules.
