Circuit board model and circuit connection method for teaching

The invention discloses a circuit board model for teaching. The circuit board model comprises a base plate, a first conductor arranged on the base plate, and an electronic component module, the electronic component module comprises a substrate and electronic components arranged on the substrate, the substrate is provided with flat interfaces conducted with pins of the electronic components in a corresponding manner, and the first conductor is connected with the interface of the electronic component module required by a circuit board so that the electronic component module forms a circuit. According to the circuit board model, the first conductor is arranged on the base plate, a second conductor is connected to the first conductor through the electronic components, a student can freely set the shape of the first conductor and the electronic components arranged on the first conductor to form a circuit diagram required by the student, the validity of the circuit diagram is tested, and the creativity of the stude
