This is a mini DC-DC step-up power module and it output fixed 5V. Using a low temperature drift 0.1% accuracy of the precision resistor, even if the board temperature rise a lot, resistance of the resistor changes less, so it does not affect the output voltage.
The greater the input voltage, the greater the ability to output current.
Can be directly soldered on the surface of experiment PCB board, easy to solder for everyone.
It is especially for Arduino, smart car, phone charger, portable charger and other items.
