The power amplifier circuit board designed using the official standard. the chip uses a selection of US imports original Longding micro Class D amplifier chip. Good product chip is necessary and the majority of music lovers to share. this is our consistent philosophy! The amplifier with ultra-high efficiency. large power. in the case of 12V power supply can output 10W + 10W of power. the chip without fins. but also with overheating. over-current protection function. the function can be said to be very powerful.
This is an LM2596 DC-DC buck converter step-down power module with high-precision potentiometer for adjusting output voltage, capable of driving a load up to 3A with high efficiency. When the output current required is greater than 2.5A(10W) an external heatsink is suggested. Use on board switch to change display measurement between the input or output voltage, and a LED indicate which value(IN/OUT) is being measured. This setting is stored even after power off. Voltmeter can be turned off, just keep the switch pressed for 1 second and leave it. Adjust Input and output voltage measurement error offset – long press switch for 4 seconds or more, the digital display flashes, then short press the button to change the value of output (values range from -0.5 to 0.5, the unit is V), a positive number indicates an upward calibration, negative downward calibration. Now press the button again for adjust input offset in same manner.
It is 18650 Mobile power bank Battery Charge, Discharge, Protection & Boost Circuit board module.You can make your own power bank using this module. It can charge up to 4 batteries in parallel.Can show the battery charge & discharge status with two mode on-board LED’.(Blink& Standby)Module comes with protection function, Overcharge protection, Over-discharge protection, Over current protection.Intelligent Overcharge protection system automatically stops charging once the connected device is fully charged. Stable Output voltage and current.
