PURPOSE: A prefabricated electronic circuit block is provided to be applicable to various shapes by separately forming a main block constructing an electronic circuit and a power supply block supplying power to the electronic circuit, thereby simplifying composition. CONSTITUTION: A main block(100) is equipped with a first connection hole to enable a power line to be inserted, and a battery is inserted into a power supply block(200) to supply power. The upper and lower sides of the main block and power supply block are equipped with multiple combining protrusions so that at least one among a decoration block(310) and a motor block can be combined. The main block and the power supply block are connected to each other by a combining unit to be inserted into the combining holes prepared on each side surface. |
