This power and light driver module PCBA is a compact, double-sided power control board for voltage conversion, lighting load control, and auxiliary device driving. Its irregular PCB outline and compact component layout suit electronic equipment with limited installation space, combining multiple power functions into a small module.
The board uses a double-sided SMT assembly structure loaded with power MOSFETs, power management ICs, SMD inductors, electrolytic capacitors, diodes, current-sense resistors, and other surface-mount components placed across both sides of the PCB. Visible connection points include HV+, LV+, and GND power terminals, plus dedicated connectors marked for a 9V fan and a lighting output. This layout lets the module support power conversion, controlled load output, and auxiliary fan operation within one single compact circuit.
For power electronics applications, reliable surface-mount assembly matters most because switching devices, current-sensing components,…
