This Red Dot Laser Module is an exciting little module capable of shining a 5mW laser light on a low-power 5V circuit. This makes it ideal for Arduino projects and basic electronics applications, as it provides a bright, focused light without requiring high voltage or complex circuitry.

This module is often used for applications like building a custom-designed laser light or a device to check the level of surfaces during construction, but could also be used for more exciting projects like creating your own security system. It is not only a unique and fun module to experiment with, but it’s also very affordable for the many different applications in which it can be used.

The PCB size of this module is a small 15mm x 24mm, making it a perfect fit for small projects with space limitations, with a super light weight of 2.2g to ensure it doesn’t weigh down your projects either. The pins include a GND pin, a 5V Input pin, as well as a Signal pin to control the operations of the module, all of which can be connected to and controlled via an Arduino Board or similar Development Platform.
