Assembly Instructions

Assembly instructions/tips: Through hole soldering. Place resistors 1, 14, 5 and 9 on back side of board before Piranha LEDs. Transistors and header plug are also mounted on the back side of the board.

Warning: silkscreen orientation icon for transistors is incorrect but Base, Collector, Emitter designations are correct. Align transistors according to BCE.
