PCA9685 16-Channel 12-Bit PWM Servo Driver Module I2C for Arduino

The PCA9685 16-Channel PWM Servo Driver Module is an I2C-controlled PWM driver that provides 16 independent 12-bit PWM output channels. It is ideal for controlling multiple servo motors, LEDs, or any PWM-driven device without consuming multiple microcontroller pins. Up to 62 modules can be chained on a single I2C bus, enabling control of up to 992 servos.

• IC: PCA9685
• PWM Channels: 16 x 12-bit (4096 steps)
• Interface: I2C (SCL, SDA, VCC, GND, OE)
• I2C Address: Configurable via 6 solder jumpers (A0–A5) — up to 62 modules on one bus
• PWM Frequency: 24 Hz – 1526 Hz (adjustable)
• Logic Voltage: 3.3V – 5V
• Servo Power: External V+ screw terminal (supports up to 6V for servos)
• Onboard 220μF capacitor for stable servo power
• Color-coded 3-pin servo headers (PWM / V+ / GND)
