The input power line and output high-voltage line need to be soldered by themselves, and the power is very high. Do not directly pull an arc on the pin, it must be led out with high voltage to prevent the arc from burning out the pin! Note: If the module is hot, it means that the ignition time is long, and it is necessary to cut off the power to dissipate heat, or increase the heat sink to work longer!<br><br>Product name: Ignition module Power: 50W Supply voltage: 9V Limit voltage: 12V (Note that this is the limit voltage, easy to break!!)
