This 4-Channel power FET driver allows 8-Bit proportional control of high-current loads using I2C communications, making it compatible with all computing platforms, including Raspberry Pi, Arduino, Particle Photon, BeagleBone, and much more.  This device uses four BUK98150-55A power FETs, allowing control of 8 channels of High-Power LED or incandescent lighting using the I2C data bus.  The BUK98150-55A is capable of controlling up to 55VDC and 5.5 Amps of current (8 Watts of Heat Dissipation), making it an ideal choice for most low-voltage DC lighting applications.  The PCA9633 chip is used as a driver for this controller, making communications easy and expandable to up to 62 devices on a single I2C port.

Take control of your DC lighting applications from any computing platform. Plug this device into a Particle Photon or Particle Electron for worldwide access using the Particle Cloud infrastructure. Plug this device into an Arduino for easy programming and quick development. Plug into a Linux using Raspberry Pi or BeagleBone for cost-sensitive applications that require some computing power. We are always developing GitHub libraries for Java, Python, and Arduino to help get you started.
