1.RF模块– 这是最基本的(也是最便宜的)无线通信方式。通常,它们在单个无线电频带(433, 868 或915 MHz)中运行,并且需要在用户端进行一些设置。RF模块的主要优点是通信距离远(可达数百米)和功耗相对较低。 2.LoRa– LoRa模块类似于上述RF模块,但使用了特殊的调制方式,使其在相同功耗的前提下可以实现更大范围的...
RF Module for Arduino The RF set is the best possible wireless pair for hobbyists. The kit comes with two parts, the receiver and the transmitter, both in the same color and quality. They arrive in anti-static packaging and have an inbuilt power manager to ensure smooth functionality. RF...
