This particular board is a model rocket launch controller. At least that's one purpose it has, really it's intended for blowing up random shit with a high voltage/high current energy pulse. It uses a camera flash charger IC and transformer to charge up a couple 180uF photoflash caps to 325V, and dumps them into whatever's connected to the output terminals through a 150A rated IGBT.Dick Butt 3D printed drone rocket?!?
IN!
It'll be mounted in a 3D printed case about the size of a Wiimote with a few AA batteries for power, and a couple of binding posts sticking out the top. SW1 is the arm switch, SW2 is the fire button, and a bicolor LED in the center gives the battery and charging status.
