    The device works pretty well ! I did the smoke-test with 4GB micro sd HC4 card and it works. Be aware that this is not a generic mp3 player and there is a special folder structure and file and folder name convention (RTFM). The speaker output is VERY powerful. If the attached speaker is with low-impedance the power source shall be able to provide enough power (current) otherwise you will get "bad" noise.

    I ordered this product somewhere in October, and they arrived today! I am very happy with them! They work great! Remember to use an external amplifier with volume control. When setting the volume with the specified commands, the chip makes a lot of noise on the audio lines. So just keep the volume all the way up, and use an external potentiometer for the volume. I wasn't planning on using the onboard 3W amplifier anyways... Great product, I am happy!

    It works but 3 items to remember 1 Speaker Out may be burned out if You use 8 Ohm speaker - please be careful. 2 In datasheet is a very very ugly error, p.6 - error in control summe, insteade of 7E FF 06 03 00 00 01 FF E6 EF command must be 7E FF 06 03 00 00 01 FE F7 EF 3 Control summe bytes - you can calculate it using equation CS= -(256*256-Bytes), it must be hex 2-byte unsigned type, Bytes - summ of all bytes of comman with exeption of 7E, EF ans control summe bytes

    These tiny modules are packed with features which rival or exceed those of complete systems. Whilst the datasheet of the main I.C. is published in the Chinese language, there is enough information to deduce the amazing feature list and implement the functions on your favorite processor. Quality product and extremely great value for money.
