16-Channel PWM Servo HAT - Get a Fast Quote & Local Stock from Communica

What is a 16-Channel PWM Servo HAT?

A 16-channel PWM Servo HAT is an add-on board designed to provide precise control of up to 16 servos or PWM-controlled LEDs from a single microcontroller. It's particularly popular for robotics projects, pan-tilt camera systems, and multi-axis automation in educational and maker environments. Based on the robust PCA9685 PWM driver, this HAT offloads timing from your Rasberry Pi, Arduino, or microcontroller, ensuring smooth motion and reliable operation even in demanding applications.

Key Features & Specifications

These HATs are frequently used in South African STEM education kits, prototyping labs, and industry settings. You'll find them powering animatronics, robotic arms, and IoT automation rigs at local hackathons, schools, and industrial testbeds alike.

Compatibility & Applications

• Works with all variants of Raspberry Pi (A/B/Zero/4/5 series)
• Compatible with standard Arduino boards and ESP32/ESP8266 devkits
• Drives any hobby servo (SG90, MG996R, etc.) and PWM-controllable LEDs
• Suitable for robotics, animatronics, model vehicles, and test applications

Why Source from Communica?

Communica makes it straightforward for South African engineers, schools, and procurement officers to buy 16-channel Servo HATs with confidence:

• Local warehousing for quick turnaround (no customs delays)
• Branch collection in Samrand, Pretoria, and Cape Town
• Thousands of components, cables, and power supplies also available
• VAT-compliant quotations and invoicing for education and industry
• Supporting major brands such as Adafruit, Waveshare, Keyestudio, DFRobot, and more

Selecting the Right 16-Channel PWM Servo HAT

When choosing a PWM Servo HAT, consider the following:

• Microcontroller Voltage: Most HATs support both 3.3V (Raspberry Pi) and 5V (Arduino), but always verify before wiring.
• Servo Current Needs: Calculate total current draw. Standard mini servos (like SG90) draw 300-500mA each under load, so a 5A-10A regulated supply is common for all 16 channels. Keep wiring short and thick to minimise voltage drop.
• Physical Fit: Ensure clearance above your Pi or dev board; check HAT stacking if you use multiple add-ons.
• I2C Addressing: If using more than one HAT, select alternate addresses with onboard jumpers.
• Library Support: Prefer well-documented HATs from brands with published Python/C++ libraries for smooth setup.

Typical Wiring Example

Pi/Arduino SDA ---- HAT SDA
Pi/Arduino SCL ---- HAT SCL
5V Supply  ------- HAT V+ (servo power)
Ground      ------- HAT GND

Always keep Pi/Arduino ground joined to servo supply ground for safe logic/servo reference.

Practical Example: Robotics Club Scenario

A Gauteng robotics club needs to independently control 16 MG996R servos for a walking robot. They select a PCA9685-based 16-channel PWM HAT, an external 5V 10A regulated supply (approx. R300-R450 ZAR, as of 2024), and a box of jumpers. Communica provides a VAT quote and confirms next-day Samrand branch pickup. The club uses Python libraries for setup and gets after-sales technical support from the Communica team.
