16-Channel PWM Servo HAT: Stock, Specs & Local Price from Communica

Expand Your Project Control with a 16-Channel PWM Servo HAT

Need to control multiple servos or LEDs from a single Raspberry Pi, microcontroller, or robotics platform? A 16-channel PWM Servo HAT provides a convenient, stackable way to drive up to 16 motors with precise, independent control. Ideal for engineering education, robotics, animatronics, or custom home automation builds, these HATs simplify wiring and free up valuable GPIOs.

Communica stocks a variety of PWM Servo HATs, including popular models from Adafruit and compatible brands. All are designed for the South African maker and developer market-with local support, VAT invoicing, and the flexibility to collect from any branch or arrange fast nationwide delivery.

Compatibility and Assembly Notes

• Fits all 40-pin Raspberry Pi models (B+, 3, 4, Zero via header adapters)
• Stackable HATs: For more than 16 servos, change I2C address and stack up multiple boards
• Comes with tested libraries for Python, Arduino IDE, and CircuitPython

Assembly is straightforward-simply connect the HAT to your baseboard and plug servo headers directly. External DC power wires may be soldered or screw-term-connected, depending on the model.
