Zusammenfassung:The utility model relates to a raspberry Pi teaching instrument, which comprises a raspberry Pi main control board and a peripheral device, the raspberry Pi main control board comprises a raspberry Picircuit board and a circuit expansion board, and the circuit expansion board is of a double-layer structure, so that the area of the circuit board can be effectively increased, and the arrangement ofperipheral pins of the raspberry Pi is facilitated; the circuit expansion board is provided with an anti-reverse-plugging interface, and the anti-reverse-plugging interface is matched with a specialwire, thereby guaranteeing that the connector cannot be plugged reversely. The anti-reverse-plugging interface orderly arranges the original peripheral pins of the Raspberry Pi and the sensor module and execution module interfaces connected to the circuit expansion board around the circuit board in sequence, and marks the names and numbers of the interfaces, so that learners can use the anti-reverse-plugging interface conve
