For a number of projects at home, I am developing an LED controller myself. The goal is to have everything in a package for small portable applications, so that the LED strips are powered and controlled by this controller. And this with only 2 AA batteries.
Everything is controlled with an Atmel Atmega32U4, and can be programmed with the USB port on the PCB.
I have developed my own version as an intern with Elektor. Tests are currently being carried out with 60 WS2812 5050 LEDs. A number of things will be adapted in the next version to improve functionality and power consumption.
And maybe there will be a powered version for larger applications.
Schematics and more info will be coming soon.
