Kit promised Red/Green LEDs. Red/Blue were received. Kit promised audio IC 9300. IC received was BJ1562. Instructions suggest 3-12 V supply may be used. My experience suggests that voltage should not be above 4.5V approximately. Audio circuit does not work. Online information for the audio IC supplied indicates that connections between audio IC, speaker, S8050 transistor and power supply should be different from the circuit on the board supplied. I can make the audio circuit operate by changing its configuration but volume is very low. (I am an experienced kit builder but not qualified as an electronics engineer).
Item is ok, but rather slow shipping!
