The Limited piece Pi

I have a challenge. Make the first 5 digits of Pi. the output will be BBBBBRBBBBRBBB. you HAVE to use ONLY 4 bits, two crossovers, and 20 green droppers ( I don’t know what they are really called) If you really need a hint, know that there is exactly enough of everything.

Challenge: try to see if you can do it without some of the stuff. I will try that.
