Rest of the parts, except the header, are shared with the GoodFET31L
Should take about 30 minutes to assemble.
If you're using this LED, and using the arrows on the board, I believe the “large U” should be on the same side as the arrow head. The cathode (negative) is the T shaped pad.
FT232, resistors, LED's and capacitors added
Plug into a USB hub, Two LED's closest to the USB port should flash momentarily. If this works, plug it into a PC and the LED's should flash a couple of times more, and the PC should install drivers.
If it doesn't flash, check orientation of the LEDs, if the USB doesn't install, check the chip for shorts or badly soldered pins.
