Datasheet — Yl105

Connect YL105 output to an interrupt pin. Count pulses per minute using a magnet attached to a rotating shaft.

Since "YL-105" is the module model number (often manufactured by generic Chinese factories), the detailed datasheet usually refers to the core IC.

Typical Arduino Library: If you are developing with Arduino, look for the "A7105" library or libraries related to the "FlySky" protocol (as the A7105 is the chip used in many FlySky RC transmitters).

The YL-105 is an adapter breakout board specifically designed for the nRF24L01+ 2.4GHz wireless transceiver module. Its primary function is to resolve common power supply and wiring issues encountered when interfacing these wireless modules with 5V microcontrollers like the Arduino Uno. 1. Key Technical Specifications

The YL-105 integrates a voltage regulator and filtering components to stabilize communication. Specification Input Voltage 5V DC (Accepts range 4.8V – 12V) Output Voltage 3.3V DC (to power the nRF24L01) On-board Regulator AMS1117-3.3 chip Max Output Current Up to 800 mA Compatibility 8-pin nRF24L01+ or nRF24L01+ PA+LNA modules Operating Temp -40°C to +125°C Dimensions 26 x 19 x 12 mm 2. Problems Solved by YL-105

Voltage Regulation: The nRF24L01 module requires a strict 1.9V to 3.6V supply. Standard Arduino 3.3V pins often lack sufficient current stability, leading to "brownouts" and dropped connections. The YL-105 allows you to use the more robust 5V rail.

Filtering: It includes on-board capacitors that act as filters to reduce noise on the power line, which is critical for stable RF transmission.

Ease of Wiring: It converts the module's 2x4 (8-pin) header into a breadboard-friendly single-row header with clearly labeled pins. 3. Pinout and Connections

The YL-105 adapter has 6 pins for interfacing with a microcontroller and an 8-pin socket for the wireless module.

YL105 Datasheet: Detailed Specifications and Applications The YL105 is a specialized electronic component, most commonly recognized as a high-performance Bridge Rectifier or a specific Integrated Circuit (IC) variant used in power management and signal processing. Because "YL105" can sometimes refer to proprietary parts in specific industrial machinery or consumer electronics, understanding its datasheet is crucial for safe circuit integration. yl105 datasheet

This article provides a comprehensive overview of the YL105’s electrical characteristics, pin configuration, and typical use cases. 1. Product Overview

The YL105 is designed for efficiency and reliability. Depending on the manufacturer (often associated with brands like Yisheng or various silicon labs), it is frequently utilized in AC-to-DC conversion modules. Its primary role is to ensure stable current flow while protecting sensitive downstream components from voltage spikes. Key Features:

High Surge Current Capability: Designed to handle momentary spikes without thermal runaway.

Low Forward Voltage Drop: Maximizes energy efficiency by minimizing power loss as heat.

Compact Footprint: Available in various packages (like SOP-8 or specialized bridge housings) to fit modern, space-constrained PCBs.

Thermal Stability: Rated for operation in industrial temperature ranges. 2. Technical Specifications (Typical Values)

If your YL105 is in a standard 4-pin Bridge package, the layout is usually as follows: AC (~): Input for the alternating current. AC (~): Second input for the alternating current. Positive (+): Rectified DC output (High). Negative (-): Rectified DC output (Ground/Common). Connect YL105 output to an interrupt pin

If it is an 8-pin IC variant, pins generally include VCC (Power), GND (Ground), FB (Feedback), and OUT (Signal Output). Consult the diagram on the physical datasheet to avoid reverse polarity, which can lead to component failure. 4. Typical Applications

The versatility of the YL105 makes it a staple in several industries:

Power Supplies: Used in the primary stage of SMPS (Switch Mode Power Supplies) for LED lighting and laptop adapters.

Consumer Electronics: Found in battery chargers for small appliances.

Industrial Automation: Acts as a signal rectifier for sensors and small motor controllers.

Telecommunications: Provides stable DC rails for networking hardware. 5. Installation and Design Tips

To get the most out of the YL105, consider the following design best practices:

Heat Dissipation: While the YL105 is efficient, at maximum current loads, it requires adequate copper pour on the PCB to act as a heatsink.

Filter Capacitors: Always place a decoupling capacitor near the output pins to smooth the rectified DC ripple. Typical Arduino Library: If you are developing with

Reverse Voltage Margin: For longevity, it is recommended to use a component rated for at least 20% higher voltage than your circuit's maximum peak voltage. Conclusion

Rough Approximation Formula (Example Only): $$ \textTurbidity (NTU) \approx -1000 \times \textVoltage + 4500 $$ (Note: This is hypothetical. Real-world calibration requires temperature compensation and specific solution mapping.)

| Parameter | Value | |-----------|-------| | Operate Point (Bop) | 10–30 mT (South pole facing marked side) | | Release Point (Brp) | 2–15 mT | | Hysteresis | 5–12 mT |

Important: The YL105 typically responds to a south magnetic pole. Bringing a south pole near the marked face turns the output LOW (active low) or HIGH depending on the comparator circuit.
