This 8-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 eight 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 PCA9634 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. Our development library makes it easy to control this device with minimal coding.

I2C expansion port makes it easy to add sensors or more controllers to the I2C bus.


This device was designed for proportional control of resistive loads, but may be used for very light inductive applications, such as small hobby DC motors. We strongly encourage customers to use this version with resistive loads as much as possible. This controller is equipped with 8 Open Collector 8-Bit PWM outputs. Open Collector 8-Bit PWM outputs work by connecting an external load, such as a incandescent light or LED to ground under software control. Open Collector 8-Bit PWM outputs are also known as low-side drivers, meaning they connect/disconnect the ground side of an external device. Because the outputs on this controller are open collector, every external load can operate at a different voltage, as long as all voltages are capable of sharing a common ground. See our wiring diagram for connection examples.

Not for use with AC power applications.

This device requires an external 12VDC Power Supply.
