Features:
With EN enable terminal, after removing the R3 resistor on the module, EN is the enable pin, and the logic is active high (boost is turned on)
Low shutdown boost (low power standby, current less than 1μA).
The level cannot exceed 5V, and the low level cannot be lower than -0.2V.

Product parameters
Input voltage: DC3-5V
Output voltage: 5V/9V/12V optional (plus or minus 0.1 to 0.2 volts up and down)
Maximum output current: 5V3.5A 9V1.3A 12V1A (MAX3.5A measured when inputting 4.2V and outputting 5V when enhancing heat dissipation, but 3A is recommended for long-term work. Please use thick wires for wiring. It is recommended not to use wires smaller than 1.5 square meters)
The output terminal cannot be connected to inductive loads such as motors, motors, fans, etc.
If the output load is frequently started or has frequent large current fluctuations, it is recommended to connect a large-capacity electrolytic capacitor in parallel to the output pad.
Conversion rate: typical 95% (related to input and output parameters)
Quiescent current is less than 1ma
Size: 14224.0mm (lengthwidthheight)
Output ripple: about 80MV

Warm reminder: Do not connect the positive and negative power inputs reversely. If you connect them incorrectly, they will be scrapped. The main chip is delicate and afraid of static electricity. Try to ground the soldering iron reliably when welding. In addition, because this module is small in size but has high current, you must use thick wires when wiring. , thin electronic wires cannot reach it!
