Character-learning building block

The invention discloses character-learning building blocks, which relate to the technical field of learning tools. The character-learning building blocks comprises building block bodies, wherein a circuit board is arranged inside each building block body, a single chip microcomputer, a voice circuit, a power module, an RS485 circuit, an STM32 minimum system and a download simulation port circuit are installed on each circuit board separately, Chinese character mechanisms are printed on the outer side walls of the building blocks, a building block host is programmed, and the single chip microcomputer determines whether positions of the building blocks can form a Chinese character; and if the Chinese character can be formed, the host reads out the pronunciation of the character, and if a Chinese character cannot be formed, the host makes no sound. The character-learning building blocks can be disassembled, combined and assembled by adopting the playing method of building blocks, and canform characters for chara
