Features:
This boost/buck module can step up or step down voltage and maintain a stable output voltage.
It has quite low output ripple voltage, for example, 20mV when output is 12V 3A, which is great for powering speaker, audio amplifier, artificial circuit, etc.
Input 5V to 30V and it can charge storage battery, lithium battery, AA rechargeable battery, or adjust constant current LED brightness.
