12V to 5V +3.3 V voltage conversion board 5V, 3.3V power supply board BenQ power board commonly used
Size: 50MM * 32MM
Output: 12V 5V 3.3V
Three interface definitions:
P2 is the power supply 12V input interface: 12V 12V GND GND
P3 is the output interface:GND GND ADJ SW 12V 12V
P4 is the output interface: ADJ SW GND GND GND 5V 5V 5V 3.3V 3.3V(1)
(BENQ12V-5V-3.3V) DC to DC circuit board 12VDC to 5V to 3.3V power supply board, 12V to 5V 3.3V power supply board, with this board to access the high pressure test tube is very convenient, the market is generally high pressure section 12V power supply, you can use this to give him 12V, and then 3.3V or 5V switch signal can be done (to access the brightness can also be connected, can be accessed by 3.3V or 5V), so you can light the lamp, and can also be used Some brands of machine, the power board can use this board instead of bad.
