2x6W DC 5V 3.7V speaker modified Stereo Bluetooth amplifier board can connected lithium battery with charge management A8-020

100% Brand New

Size: 7x4x0.7cm

Conversion:1cm=0.39inch /1 inch =2.54cm
shared：



Feature:
Bluetooth power amplifier standby standby small stereo sound quality is better for small Bluetooth
speakers use
Output power 6W + 6W dual channel stereo
Applicable speaker impedance: 4 ohms,6 ohms, 8 ohms (speaker impedance is too small will have
the volume to open a large sound
Power supply voltage: 5VDC or 3.7-volt lithium battery (used in the battery is too long battery voltage
is too low will have a little volume to open the big sound phenomenon)
Supply current: enough power of 1A or more (power supply current is not enough to use the
volume of the General Assembly will appear off the phenomenon)
Charging interface: the use of lithium battery power supply, the charging interface 5 volts power
supply or mobile phone charger can charge a single lithium battery
(Charge management circuit on the battery limit the maximum voltage of 4.2VDC)
Friendly reminder: When the sliding switch ON Micro USB port is the charging port,
powered by the lithium battery to work, slide the switch OFF when the Micro USB port is
the power supply port, you can not take lithium battery work.
