A kW-scale RGBW LED controller for indoor effect lighting. I designed this board in my sophomore year of high school because no low-cost, highly-programmable RGBW solution existed at the time. The two TSSOP parts (PCA9685 16ch PWM controllers) were the first SMT parts I soldered.
My second time using Autodesk Eagle. I didn't know pin labels were a thing, so all wires are directly routed from input to output. I'm so sorry! :P Also, an interesting story about the big power MOSFETs: the only ones I could find that were in my budget came from an obscure eBay listing. I ended up waiting about a month just to put the final parts on the board because shipping took so long!
A fairly decent design, I think. I didn't know about ground pours at the time, so I manually routed large ground traces to all of the power MOSFETs.

The Arduino code includes two libraries: Thread (https://www.arduino.cc/reference/en/libraries/thread/), and PCA9685 (https://www.arduino.cc/reference/en/libraries/pca9685-16-channel-pwm-driver-module-library/). These two links have installation instructions and are supported by the Arduino Library manager.
