ShiftBar - RGB LED Controller

Produktbeschreibung

The ShiftBar is a 3-channel constant current LED driver module by macetech based on the Allegro A6281. This is a carrier board that is similar to the ShiftBrite, but designed for controlling external RGB LED modules such as the ultra-bright Satellite Module 001. Using just three digital output pins and a simple protocol, your microcontroller can control a long chain of ShiftBars. Each ShiftBar in the chain can be independently changed to any of the 1,073,741,824 possible colors to create dynamic displays and decorations.

• Supplies 10 mA to 150 mA per LED channel.
• On-board potentiometer for current control.
• Input voltage range from 5 V to 17 V, with no separate logic supply required.
• Overtemperature shutdown protects the LED driver from overheating.
• Adjustable current for each color channel lets you correct for slight differences in brightness.

Example ShiftBar applications

An example setup using a Micro Maestro to control a ShiftBar (or chain of ShiftBars) is shown below. Digital outputs 0, 1 and 2 are used to send the control signals to the clock, latch, and data lines, the enable line is connected directly to GND, and 12V power to the Maestro is delivered from the ShiftBar chain. Maestro source code to control a ShiftBar is available in the Example scripts section of the Maestro User’s guide.
