基于nRF24L01可充电多媒体激光笔的设计

The Design of Rechargeable and Portable Multimedia Laser Pointer Based on nRF24L01

针对目前市场上大多数多媒体激光笔不具备便携充电等的缺点,结合nRF24L01无线传输技术与锂电池充放电管理技术,设计制作了一款能够利用USB电源进行充电的便携式多媒体激光笔。该便携式多媒体激光笔具有体积小、功耗低、性能稳定等特点。

Most of multimedia laser pointers are not portable and rechargeable in the market, and a portable multimedia laser pointer charged with USB power source is designed. The wireless transmission technology based on nRY2401 and the Lithium Battery＇s charge and discharge management are applied in the design. It consists of handheld transmitter and PC-receiver. The transmitter has four modules： MCU-module, charging module, wireless transmission module and keyboard module; And the PC-receiver has a wireless MCU-module, a receiver module and a USB communication module. The multi-media laser pointer is compact, easy to use, and of low power consumption.
