3.3V Neopixel driver

Two weeks ago we got an assignment in our university college: make a VHDL driver for the neopixel from adafruit. There was one small problem, the FPGA board we use is the Digilent Zybo, which drives it’s outputs at 3.3V and the neopixel matrix needs 5 volt on its data in pin. Because I hate working with breadboard beyond an early prototype phase I quickly drew up a PCB design. Uploaded it to PCBWay and a couple of days later DHL dropped of some really nice PCB’s. Great job PCBWay!
