Hey those LED modules appear to be the same ones I have. Note the circular forms under the long bar lens. The long bar lens I found from one of my calculators is a good match to that tan board one, and if I lay some bubble top modules under it, it recreates the squished bubble shape visible.
Also, I don't know why I thought to worry about my circuit trace layout after seeing this board, it has nine LEDs, and much closer together than the seven module board. I think the only question on my end that keeps me from ordering a batch of these is if it's tan/natural color or blue.
I guess I could get one set of each?
