Kit parameters:
Supply voltage: DC 4.5V-5.5V;
PCB board size: 103.6MM*87MM
Acrylic shell size: 117MM*100mm*21MM
it have 30 kinds of pattern LED rotation effect
Note 1: Please solder it refer to the PCB mark. Most of the triodes are 8550, one of which is 8050. Please pick this out when soldering. (There are 2 devices on the PCB board, one writes 8050 and one writes MUSIC. This is because the current music IC has 2 kinds of packages, one is COB, and the other is T0-92, so it is compatible with 2 kinds of music ICs. If the music IC is COB package, the transistor 8050 is soldered on the music IC. if the music IC is packaged in T0-92, the transistor 8050 is soldered on the PCB.)
Note 2: Music IC song is For Alice.
