+
+E18-MS1PA1-PCB采用美国德州仪器（TI）公司原装进口CC2530射频芯片，芯片内部集成了8051单片机及无线收发器，并适用于ZigBee设计及2.4GHz IEEE 802.15.4协议。模块引出单片机所有IO口，可进行多方位的开发。该模块内带功放芯片CC2592，增加了无线通信距离。

+
+DL-30无线串口模块为串口转2.4G无线模块，可以通过无线将两个或多个串口连接起来。串口发入模块的数据会被模块使用无线发出，收到无线数据的模块会将这个数据使用串口发出，在两个设备上使用模块就像将这两个设备用串口连接起来一样。
+
+| 射频参数 | 值 |
+| --- | --- |
+| 工作频率 | 2400~2450MHz |
+| 发射功率 | 4.5 dBm |
+| 传输速率 | 最高3300Bps |
+| 接收灵敏度 | -97dBm |
+| 传输距离 | 250米（室外空旷无遮挡） |
