What is the 18Ch PWM LED Driver?
A total of 18 LEDs can be powered and controlled using this PWM LED Driver, you can also utilise a range of pins to run bi-colour and RGB/W LEDs. Allow your Arduino or Raspberry Pi to have better control over a large range of LEDs through the I2C connection in this tidy discreet breakout board.

A breakout board allows you to make difficult to solder, or a group of parts easy to integrate into your projects.
Convenient M3 holes in the PCB make mounting this breakout into your project easy.

How to get the most out of your project?
If using with a Raspberry Pi you can use the 3.3 V supply to power the chip (via the VCC pin on the breakout board) and the 5V supply to power the LEDs.
The header pins allow for quick and easy attachment to a breadboard allowing for all your prototyping and testing needs without messy wires. The header pins do not come attached, enabling you to attach wires instead - this is great for more permanent application.
There is a dedicated Library already available, helping your projects run smoother and faster, available here

Can this be used to drive DC motors ?

Asked by: Shalianahe
Unfortunately we are unable to guarantee full compatibility for this item with motors, as this is not the manner for which it was designed to be used.
