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

SKU CH-JF1M-6EZJC

Controls up to 16 servos or PWM outputs with 12-bit resolution over I2C, includes a 5 V regulator for battery power, and fits Raspberry Pi or Jetson Nano via 40-pin header

  • Controls up to 16 servos with 12-bit precision
  • Uses only two GPIO pins via I2C control
  • On-board 5 V regulator delivers up to 3 A
  • Compatible with Raspberry Pi 40-pin header and Jetson Nano
  • Works with standard servos including SG90, MG90S, MG996R

Servo Driver HAT for Raspberry Pi and Jetson Nano

This development board adds sixteen PWM channels to a Raspberry Pi or Jetson Nano through the standard 40-pin GPIO header. It communicates over I2C using only two pins, leaving the remaining GPIO free for other tasks. The board suits robotics and automation projects that need coordinated servo movement.

16-Channel 12-bit PCA9685 capacity and headroom

Each channel delivers 12-bit resolution, giving 4096 discrete steps for smooth position control. The integrated 5 V regulator supplies up to 3 A, so the board can drive multiple standard servos such as SG90, MG90S or MG996R from a single power source. Projects requiring more than sixteen simultaneous channels or higher per-channel current will exceed the board’s capability.

Right-angle pinheader and reserved I2C pins

The right-angle pinheader keeps the HAT’s profile low inside enclosures and allows stacking with other HATs. Reserved I2C control pins let the PCA9685 be driven from alternative microcontroller boards without rewiring. No additional software libraries or configuration tools are bundled; users must provide their own I2C driver code.

Questions about this item

Will the 40-pin header on the LORDWORLD Servo Driver HAT (B) fit my older Raspberry Pi 3 Model B?

Yes, the standard 40-pin GPIO extension header is compatible with Raspberry Pi series boards including the Pi 3 Model B.

How can I verify the PCA9685 is communicating correctly after I connect it via I2C?

Run an I2C bus scan; the PCA9685 should appear at its default address, confirming the 2-pin link is active.

Does the package include the SG90 or MG996R servos listed in the compatibility notes?

No, the board supports common servos such as SG90, MG90S and MG996R but they must be purchased separately.
