It appears to me that one could connect all four on the right side to the left side via one properly sized resister to adjust the voltage to 5V. Is there a hole in the board on the left side (the 12V side) that could be jumped over via a standard resister to the hole that shows up on the right side? If so, then connecting the other three to that strip (via a copper wire) would supply the voltage to all four without the necessity of soldering the smt resister pack??? Yes? No?
