This module was purchased to enable me to play music stored on my tablet, through my old Rotel amplifier and attached speakers, and also through Logitech powered speakers via Bluetooth. In the absence of any written instructions (my only quibble), I followed the diagram on the web site. Bluetooth connectivity was fast and straightforward and the quality of the sound produced is probably as good as the amp. and speakers can handle. I would have appreciated some information about the enclosed connectors and their use. A very satisfactory purchase.

Good module. Works by receiving a Bluetooth signal from a tablet or mobile phone. Powered by a micro USB 5 volt DC supply. The unit can be powered by an 18650 Li on battery, 3.7v to 4.2v Note the USB disk port may not read the memory at less than 5 volts The USB disk port and the micro sdcard works with wav and MP3 files. Data cannot be sent from the memory cards via Bluetooth this only outputs to the local stereo 3.5mm jack socket. Ideal for a custom Bluetooth amplifier and speaker setup. The Bluetooth range can be increased by soldering a 40mm length of solid core wire to the tip of the pcb antenna
