16-Channel PWM Servo HAT - In-Stock South Africa | Communica

Expand Your Robotics with a 16-Channel PWM Servo HAT

Looking to control multiple servos for your robot, animatronic, pan-tilt rig or smart device? The 16-channel PWM Servo HAT delivers a quick, reliable solution-no GPIO pin limitations, no complex timing code. Popular with South African makers, students, and engineering teams, these HATs are purpose-built for flexible, multi-axis motion using boards like the Raspberry Pi, Arduino, or ESP32.

Why Choose a 16-Channel PWM HAT?

• Control up to 16 servo motors (or LEDs) with precise PWM from a single I2C interface
• Chain several HATs to drive up to 62 devices (up to 992 servos!) using unique addresses
• Free up your host's timers/IO for sensors and logic

Spec Comparison Table

Communica offers trusted brands, including Adafruit, Seeed Studio and Waveshare. Choose your preferred module based on platform, form factor and mounting requirements.

Compatible With:

• Raspberry Pi (all 40-pin models)
• Arduino UNO, Mega, Nano, Leonardo
• ESP32/ESP8266 (with I2C support)
• Micro:bit and STM32 (with suitable wiring)

Libraries and examples are readily available through official and open-source repositories, making them ideal for quick project development and educational robotics.

Typical Applications in South Africa

• Robotics club builds-multi-legged walkers, bipedal bots and articulated claws
• Automation and prototyping-servo-actuated levers, camera rigs, animatronics for school projects
• Tertiary engineering competitions and industrial demonstration rigs

Many tertiary institutions and technology schools use these HATs for hands-on labs, automation demonstrations, and open-ended design challenges. Faster access to local stock means minimized lead times and repair cycles for South African teams compared to importing yourself.

Key Specifications & Buying Advice

• Power input: Most boards require a separate 5V-6V supply for the servo rail. (Host MCU power is often not enough; plan accordingly.)
• PWM frequency: Adjustable (typically up to 1.6kHz). Standard servo control uses 50Hz.
• Communication: I2C (default address 0x40, configureable up to 62 boards chained together).
• PWM output drive: Each channel uses a dedicated 12-bit output, for smooth servo movement.
• Mounting: "HAT" (stacked) for Raspberry Pi; pin-headers or DuPont for Arduino/others; enclosure mounting possible for field/industrial.

Wiring Example (Basic Raspberry Pi Setup)

     +-------------------+                          +----------------------+
     | Raspberry Pi      |    I2C   (SDA,SCL)       | 16-Ch Servo HAT      |
     | 3.3V, GND         |------------------------->| VCC, GND, SDA, SCL   |
     +-------------------+                          +----------------------+
                                            |
                                            | (External 5-6V supply)
                                            |
                                     +--------------+
                                     | Servo Motors |
                                     +--------------+

Always check your servo current draw-small hobby servos may only need 100-250mA each, but large units can draw 1A+ on stall. Multiply by the number of servos and add a 20% margin.
