Description

When developing complex robotics, animating intricate art installations, or driving numerous LEDs with specific PWM signals, microcontrollers often face limitations in the number of available PWM outputs. The 16-Channel I2C PWM Servo Driver Module Shield provides an elegant solution, enabling control over 16 independent PWM channels using only two I2C pins from your main microcontroller.

This module features an I2C-controlled PWM driver with an built-in clock, eliminating the need for continuous signal transmission from your microcontroller. It is 5V compliant, allowing control from 3.3V microcontrollers while safely driving outputs up to 6V. With 6 address select pins, up to 62 of these breakouts can be chained on a single I2C bus, providing a remarkable 992 PWM outputs for large-scale projects. The module delivers adjustable PWM frequency up to 1.6 KHz and 12-bit resolution per output, ensuring highly accurate control for applications like servo positioning.

Designed for ease of use, the breakout board includes a terminal block with reverse polarity protection for robust power input, alongside a power-good LED. It offers 3-pin connectors for direct servo plug-in and incorporates 330-ohm series resistors on all output lines for protection and simplified LED driving. Configurable push-pull or open-drain output modes enhance versatility, making this shield an essential component for projects requiring extensive PWM capabilities.

Frequently Asked Questions

What is the maximum number of servo drivers that can be chained together?

This shield features 6 address select pins, allowing you to chain up to 62 individual modules on a single I2C bus. This configuration provides a total of 992 independent PWM outputs, suitable for very large-scale projects like complex robotic arrays or extensive LED matrices.

What power requirements does this servo driver shield have?

The module has an independent V+ input for servo power, supporting up to 6V. Logic signals operate from 3V to 5V, making it compatible with various microcontrollers. A terminal block with reverse polarity protection ensures secure power connections.

What is the resolution and frequency range of the PWM output?

Each of the 16 PWM outputs offers 12-bit resolution, providing approximately 4 microseconds of precision at a 60Hz update rate. The adjustable PWM frequency ranges from 40 Hz up to about 1.6 KHz, accommodating different servo types and LED dimming requirements.

How does the I2C control reduce microcontroller overhead?

This driver integrates a built-in clock, making it completely free-running. Unlike PWM solutions that require continuous signal generation from the microcontroller, this module handles the PWM generation internally once configured via I2C, freeing up the microcontroller for other tasks.

Can this shield drive both servos and LEDs?

Yes, it is versatile enough to drive both. Its precise 12-bit PWM output is excellent for controlling servo positions, while the configurable output (push-pull or open-drain) and integrated 330-ohm series resistors on each line make it suitable for driving LEDs directly.
