I spent a lot of time manually routing that board. So the GND and 5V connections are all done with copper fill for maximum stability. Each Falcon power pin is wired to the copper fill, along with the simm power pins. I've added on 100uF ceramic also.
Or those those using a crappy browser https://www.youtube.com/watch?v=OptI6zeYMe8
If there is still demand for these then I will get a small run done sometime after xmas.
