M5Stack Laser.Tx - a Laser Emitter Unit

Description

The M5Stack Laser TX is a compact laser emitter unit for building line-of-sight laser communication links with M5Stack controllers. Unit Laser TX uses a laser diode as its core component and is designed to pair with the LASER.RX receiver unit for free-space optical communication experiments.

Laser communication uses the atmosphere as the transmission medium, while the operating principle is similar to an optical fiber link. Because this emitter does not require radio broadcast rights, licensing, or buried cable, it is useful for educational demonstrations, prototype communication links, and controlled projects where a visible line of sight can be maintained.

With 5V operation, a Grove interface, adjustable laser focusing, LEGO-compatible mounting holes, and Arduino/UIFlow development support, the M5Stack Laser TX gives developers a small laser transmitter unit for learning, testing, and building optical communication projects.

Warning: Lasers can cause harm to the human body. Do not aim this product at people, and prevent the laser beam from entering the eyes to avoid injury.
