In this post, we’ll break down everything you need to know: pinout, specifications, typical applications, and how to safely interface it with microcontrollers. The YL-105 is a laser diode module that emits a visible red beam (typically 650nm wavelength). Unlike a simple laser pointer, this module is designed for electronic control — you can turn it on/off digitally or modulate the beam at high speeds (useful for data transmission). | Pin | Label | Description | |-----|-------|-------------|
