The ShiftBar is a medium-power RGB LED controller, capable of powering three channels of LEDs from 10mA to 150mA and from 5V to 17V. It’s ideal for many common-anode RGB LED bars, such as the Satellite Module 001. It uses the same A6281 controller as the ShiftBrite, with daisy-chainable SPI communication that is simple to use with any microcontroller. Each channel is controlled with its own 10-bit PWM register and 7-bit current control register. A trim potentiometer allows the user to adjust overall current limiting to any desired maximum.

The ShiftBar includes six screw terminal headers for wiring your own LEDs, as well as independent power. It also has two 6-pin headers that bring power and communications into and out of the device. Chains longer than four ShiftBars at maximum current should have power attached periodically, to counteract voltage drop along the power wires of a long chain.

ShiftBar Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

  • I use the “Satellite Module 001” and “ShiftBar” to make the Installation for this ark performance.

    Thanks for developing these products :))))
