Part name: turbofan engine model Compact, functional turbofan engine model designed for use as an electronic module in smallscale projects and displays. The smallest turbofan model in its line, it combines full operational features with a spacesaving footprint. Key benefits Small size for tight spaces: at 120*80*50mm, the model fits into compact builds without sacrificing functionality. Readytointegrate electronic module: communicates over the serial peripheral interface (SPI) for straightforward connection to controllers and development boards. Simple, selfcontained power: runs on 2 No. 7 batteries with a hidden battery box that keeps the exterior clean and unobstructed. Clear visual feedback: a blue LED illuminates during operation to indicate active status. Lownoise operation: the inertial silent motor provides smooth performance with minimal sound, suitable for display and testing environments. Main features Material: plastic Size: 120*80*50mm Colors available: red, blue, green, yellow Product type: electronic module Communication interface: serial peripheral interface (SPI) Power supply voltage: 1.85.5 volts Power source: 2 No. 7 batteries; hidden battery box Indicator: blue LED light during operation Motor: inertial silent motor for quiet performance What is included 1 turbofan engine model Practical applications Scale models and dioramas: add realistic turbofan visuals and motion to aircraft models where space is limited. Educational projects and labs: demonstrate fan operation, motor control, and SPI communication as part of electronics or engineering coursework. Prototype devices and displays: integrate as a compact, lownoise airflow or visual effect module in concept prototypes, kiosks, or exhibition pieces. Why choose this model This turbofan engine model is intended for users who need a fully functional, compact module with easy electronic integration. Its small form factor, SPI compatibility, battery operation, and quiet motor make it a practical option for modelers, educators, and prototype developers requiring reliable performance without a large footprint.
