: A good datasheet often includes application notes or reference designs that can help in integrating the component into your project.
Stable voltage supply for mobile phones or GPS devices. How to Confirm Your Part Since "YL" can be a manufacturer-specific prefix: yl105 datasheet better
The (often designated as YL105 ) is primarily known as a specialized power adapter board designed for the nRF24L01 wireless module. While the name can also appear in industrial metal contexts (like the L105 aluminum alloy), its most common "datasheet" usage refers to this essential electronics component.

– it’s cheap, easy to use, and gives both analog and digital outputs. No, for professional use – lacks calibration, corrosion protection, and official documentation. While the name can also appear in industrial
| Parameter | Value / Range | Source / Note | |-----------|---------------|----------------| | Supply Voltage | 3.3V – 5V DC (±5%) | PCB regulator (none) – direct to LM393 | | Quiescent Current | ~5mA (no IR LED) + 15mA IR LED | Calculated | | Output Type | Digital (DO): Active low (0V when obstacle detected) | Open-collector via LM393 | | Output Sink Current | Max 20mA (DO) | From LM393 datasheet | | Analog Output (AO) | 0V to VCC (inverse relationship with reflection) | Phototransistor voltage divider | | IR Wavelength | 940nm typical | Standard IR LED | | Detection Range | 2cm – 30cm (depends on object color/reflectivity) | Empirical, not guaranteed | | Response Time | < 10µs (digital output) | LM393 response + optical | | Operating Temp | 0°C – 70°C | Limited by LM393 commercial grade |
The (also known as the HW-200) is the "missing link" that helps you achieve the stability described in those technical specifications. By integrating a dedicated voltage regulator and breakout headers, it solves the two most common points of failure in wireless projects. The Core Problem: Power Instability
