Sensing device, ball shaft for smart magic cube, and smart magic cube

A sensing device for smart magic cube, comprising:

• a master circuit board;
• and
• a slave circuit board;
• wherein the master circuit board defines a micro control unit, the master circuit board comprises a first circuit board and a second circuit board, the first circuit board is arranged on a front side of the master circuit board, and the second circuit board is arranged on a reverse side of the master circuit board;
• a plane rectangular coordinate system is built by setting a center of the first circuit board as an origin, setting a positive direction of an X-axis as a first direction, setting a negative direction of the X-axis as a third direction, setting a positive direction of a Y-axis as a second direction, and setting a negative direction of the Y-axis as a fourth direction;
• a first electronic sensing element, a second electronic sensing element, a third electronic sensing element, and a fourth electronic sensing element are correspondingly arranged in each of the first direction, the second direction, the third direction, and the fourth direction;
• a fifth electronic sensing element is arranged in a central area of the second circuit board;
• each of electronic sensing elements is in communication connection with the micro control unit;
• and the slave circuit board is arranged on a preset plane parallel to the first circuit board, wherein the preset plane and the second circuit board are separated on both sides of the first circuit board, the slave circuit board defines a sixth electronic sensing element, and the sixth electronic sensing element is in communication connection with the micro control unit.
