Elecbee Laser Tx Laser Emitter Module with Adjustable Focal Length for Arduino - products that work with official Arduino boards

Description:

This is one of the communication devices among M5Units, a Laser emitter with adjustable focal length. It is mainly built with a laser diode 

Laser communications devices are wireless connections through the atmos phere. 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 be nefit 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.RX 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

1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the mas ter through simple steps, and a series of function verification can be performed.

2.After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, click "Burn" to start burning. (For M5StickC burning, please Set the baud rate to 750000 or 115200)

3. Currently EasyLoader is only suitable for Windows operating system, compatible with M5 system adopts ESP32 as the control core host. Before installing for M5Core, you need to install CP210X driver (you do not need to install with M5StickC as controller)Click here to view the driver installation tutorial: https://docs.m5stack.com/#/en/related_documents/M5Burner?id=install-usb-driver
