[Embeded Linux] 2.4G DL : 0: 2.4G 产品应用比较广泛，有些芯片性能也很不错，但价位都比较偏高，很难进入量产的产品。为降低成本JF24D模块采用裸片绑定，虽然性能指标略低于具有代表性的 nRF2401 CC2500 A7105但它的价格要比它们低很多，完全可以满足一般需要双向数据传输及双向遥控的短距离产品应用。 -2.4 G products are widely used, some chip performance is also very good, but prices are high, it is difficult to enter mass production of the product. JF24D module adopts the bare chip binding to reduce cost, although the performance index is slightly lower than the typical nRF2401 CC2500 A7105 but its price is much lower than they are, can meet the needs of the general short product application of two-way data transmission and remote
