LORDWORLD 16 Channel 12-bit PWM Servo Driver HAT (B) PCA9685 development board

SKU CH-KTS5-RV976

16-channel 12-bit PWM servo driver HAT with PCA9685, 40-pin GPIO header for Raspberry Pi and Jetson Nano, I2C control, 5V 3A regulator, standard servo connectors

  • Drives up to 16 servos simultaneously using only two I2C pins
  • 12-bit resolution gives 4096 precise steps per channel for smooth motion
  • On-board 5 V regulator delivers up to 3 A from battery via VIN terminal
  • Standard 40-pin GPIO header fits Raspberry Pi series and Jetson Nano directly
  • Includes Python examples for Bluetooth and WiFi remote control projects

16-Channel 12-bit PWM Servo Driver HAT (B)

This PCA9685 development board adds sixteen independent PWM outputs to a Raspberry Pi or Jetson Nano. Each channel delivers 12-bit resolution for precise servo positioning. The board targets makers building robots, pan-tilt rigs or multi-servo automation projects.

Check your host board and power source

Verify that your Raspberry Pi model provides a standard 40-pin GPIO header; earlier 26-pin models will not mate with this HAT. The on-board 5 V regulator supplies up to 3 A from the VIN terminal, so confirm your battery or supply can meet the peak draw of every connected servo.

Integration into a build

The driver communicates over I2C using only two GPIO pins, leaving the remaining header free for sensors or displays. Reserved I2C pins allow chaining additional control boards without extra host ports. Standard three-pin headers accept common servos such as SG90, MG90S and MG996R directly. Python examples for Bluetooth and Wi-Fi remote control are included to accelerate development.

Questions about this item

Does the HAT include the servos or do I need to buy SG90, MG90S or MG996R units separately?

The board provides 16 standard servo connectors for SG90, MG90S, MG996R and similar servos; the servos themselves are not included and must be purchased separately.

Should I pick the 12-bit PCA9685 version or a different resolution for my project?

This HAT uses the PCA9685 driver with 12-bit resolution giving 4096 steps per channel across all 16 outputs; no alternative resolution variant is offered for this model.

What does the 12-bit 4096-scale resolution mean when I drive a servo from a Raspberry Pi?

Each of the 16 channels divides the PWM range into 4096 discrete steps, so a standard servo receives fine position control over its full travel when driven via the I2C link.
