 ***LASER.RX*** is one of the communication devices among M5Units, a Laser receiver. It is mainly built with a laser transistor.
 Laser communications devices are wireless connections through the atmosphere. They work similarly to fiber-optic links, except the beam is transmitted through free space. While the transmitter and receiver must require line-of-sight conditions, they have the benefit of eliminating the need for broadcast rights and buried cables. Laser communications systems can be easily deployed since they are inexpensive, small, low power and do not require any radio interference studies.
-Two parallel beams are needed, one for transmission and one for reception. Therefore we have a LASER.TX parallelly.  Port type of this unit is PORTB.

 *warning!!! laser is dangerous for human being, Don’t aim a laser pointer towards a person’s head. This is to prevent the beam from getting in their eyes, possibly causing eye damage. Remember that people can move unexpectedly, so keeping away from their heads is a good idea*

 ## 描述
 
 **LASER.RX** 是一款激光接收器Unit,内部主要由激光晶体管构成.
-激光通信设备通过大气的无线连接。 除了光束通过自由空间传输外，它们的工作方式类似于光纤链路。 虽然发射器和接收器必须要求视距条件，但它们的好处是不需要广播权和埋地电缆。 因其小巧，低功率并且不需要任何无线电干扰研究的特点，激光通信系统可以很容易地部署到各个位置.该Unit使用的端口类型为 PORTB.
