Overview

Instead of using up your limited number of PWM lines, or trying to fake it all in software (and using up all the resources on your microcontroller), you can simply pop a signal over to this chip via I²C to tell it which of 16 lines you want to pulse, with 12-bit levels of accuracy. And it'll keep doing it, all by itself. Pretty handy.

The kit comes mostly assembled, with a set of 3x4 headers for installation of servo/LED plugs, a 2-pin power terminal block, and a 6-pin 0.1" header for breadboard-compatibility.

Features

• 5V compliant, but can communicate with a 3.3V microcontroller.
• 6 "address select" pins for configuring up to 62 ICs on a single I²C bus
• Can control 16-channel PWM output
• Independent signal and power logic
• PWM frequency adjustable up to approximately 1.6 kHz
• Configurable as push-pull or open-drain output
• Output enable pin available for outside-the-microcontroller "shut it down!" control.

Specifications
