Pre-soldered onboard to smooth power delivery and improve RF range stability. Pinout Mapping & Connections
On-board bypass and decoupling capacitors help filter electrical noise, which is a leading cause of packet loss and failed transmission in RF circuits. yl-105 datasheet
For most hobbyist applications, the Beta formula suffices:
Add a 10µF capacitor between SIG and GND. Also, use averaging in your code (e.g., take 10 readings and divide by 10). | Sensor | Type | Output | Range
In this post, we’ll break down everything you need to know: pinout, specifications, typical applications, and how to safely interface it with microcontrollers.
Many people confuse the YL-105 with the laser module. The KY-008 uses a 3-pin but has a different pinout (SIG, VCC, GND) and often includes a smaller driver board. The YL-105’s potentiometer is typically easier to adjust. Always check the silkscreen labels. Also, use averaging in your code (e
The YL-105 is a reliable, low-cost laser transmitter perfect for . While you won’t find a 50‑page official datasheet, the key specs above cover 99% of use cases. Always remember laser safety — and have fun building optical projects!
While the standard nRF24L01+ module has a 2x4 male pin header that is not breadboard-compatible, the YL-105 breaks these pins out into a single row, making it easy to use with Arduinos and standard breadboards.
