This is a kit, which mean you will receive a pack of components, you need to assemble them together to use. 

also, the manual is in Chinese, there is a schematic in the Chinese manual, there is no English manual. this mean you need to use the schematic only to finish the soldering and assembly, you will need to have knowledge to identify the components type and the know to read the schematic, or it will not work for you. please consider this before buy it.

thanks
