16-Channel PWM Servo HATs for Sale in South Africa - Full Range at Communica

16-Channel PWM Servo HATs for Robotics & Maker Projects

If you're building robotics, animatronics, or automation projects, a 16-channel PWM servo HAT lets you control multiple servos precisely from one controller. Popular in education, prototyping, and industry, these add-on boards enable flexible, synchronized motion for robots, pan/tilt systems, model displays, and more.

Communica stocks a range of 16-channel PWM HAT boards, compatible with Raspberry Pi, Arduino, Espressif, and other popular platforms. Whether you need a reliable solution for an academic lab or industrial prototype, you'll benefit from local inventory, clear compatibility info, and the convenience of branch collection across South Africa.

What is a 16-Channel PWM Servo HAT?

A 16-channel PWM HAT or shield plugs into your microcontroller (like a Pi's GPIO or Arduino header), offloading servo PWM generation using dedicated hardware (typically a PCA9685 IC). This allows you to drive up to 16 standard R/C servos-each with independent pulse width, frequency, and position control-without taxing your board's timers or CPU.

• 16 outputs for standard servo or LED dimming
• 12-bit resolution for smooth movement (0.24 degrees steps typical)
• Chainable on some brands for expanding further
• Can simultaneously control servos, LEDs, or other PWM loads
• Typically powered via dedicated screw terminal (supports 4.8-6V for servos)

Compatibility & Popular Use Cases

Most 16-channel PWM HATs on the market feature I2C control, making them compatible with a wide range of host boards:

• Raspberry Pi (all models)
• Arduino Uno/Mega/Leonardo
• Espressif ESP32/ESP8266 (with level shifting if needed)
• Micro:bit & other educational SBCs

Locally in South Africa, these HATs are commonly used for:

• STEM classroom demos and robotics clubs (easy multi-servo control)
• Automation/PLC prototyping in industrial training
• Animatronics for displays, theatre props, or interactive exhibits
• 3D-printed robots with six or more degrees of freedom

Product Selection Advice

Choosing the right 16-channel PWM HAT depends on your host board, servo type, and supply voltage:

• Confirm your controller: Pick a HAT, Shield, or breakout format to suit Raspberry Pi or Arduino.
• Check I2C address settings if using more than one HAT in a chain.
• For higher torque servos (over 1A per channel), ensure the power input block and PCB traces can carry the needed current.
• Look for features like indicator LEDs, stacking headers, and software libraries (Python, C++, Arduino IDE).

Practical Example: Connecting a Servo to a PWM HAT (ASCII Diagram)

 +-- Power Input (5V from PSU)

Supply power for servos from a dedicated 5-6V DC adapter (not the Pi's USB), especially when driving multiple high-current servos. For power supplies, see Communica's Power and Accessories ranges.
