For 78XX Regulator Circuit Module PCB
78xx Series of positive voltage regulators for the same module that you can use for different pcb drawings circuits, but are drawing on the pcb the pcb 2 coolers of diode bridge rectifier, filter capacitor has just enough to connect the dc output of the transformer, etc sources (pc power supply, dc adapter, etc.) If you want to use, you don’t have to actually use the dc source with 1000f capacitor bridge diyotada you don’t have to, but at least if the reverse connection acts as the cost of protection for important it:)
