I searched for a specific "YL-105" datasheet, but it is (like for a major IC, transistor, or sensor). This code is most likely used in one of two contexts:

The YL-105 is a type of electromagnetic relay, which is an electrically operated switch that is used to control the flow of electrical current in a circuit. It is a compact and reliable device that is widely used in industrial control systems, power supplies, and other applications where a high degree of reliability and precision is required.

Depending on your project, the "datasheet" you need will cover either an infrared security device or a power stabilization board for nRF24L01 modules. 🏗️ Version 1: YL-105 Transceiver Adapter Module

High-efficiency AMS1117-3.3 regulator ensures the wireless module receives stable power. Filtering Capacitors:

The YL-105 offers several benefits, including:

This is a breakout board designed to solve the common power issues of nRF24L01 wireless modules. It includes a voltage regulator (AMS1117) that allows you to power the radio module using a 5V source instead of its native, sensitive 3.3V requirements. 4.8V to 12V DC. Output Voltage: Stable 3.3V (regulated for the nRF24L01).

DC 4.8V to 12V (typically powered via the Arduino 5V pin). Output Voltage: Fixed 3.3V.
