ꢀꢀꢀꢀEasy Usage
- Output Voltage Setting
ꢀWhen 5pin is open, set the Output to 3.3V or 5V
- How to adjust the Output Voltage
ꢀPut an adjustable resistor (fixed resistor) between 5pin and 4pin, and
ꢀset to 1.8V-3.3V or 3V-5V.
- ON/OFF Control: Output ON
ꢀWhen 1pin is open, output will either be 3.3V or 5V.

ON/OFF CONTROL
The SIP and DIP type have a plastic coating.
The SMD (SM) type is not coated, because it has a mounting suction.
