The YL-105 is a commonly used 433MHz Superheterodyne Wireless Receiver Module. It is frequently utilized in low-cost wireless communication projects, such as remote control systems, home automation, and sensor data transmission.
Because it is a generic Chinese module, there isn't a single official manufacturer datasheet like you would find for a major IC (e.g., from Texas Instruments). However, the module is built around a specific RF chip, and its specifications are well-documented in hobbyist electronics.
Here is the comprehensive datasheet and guide for the YL-105 module.
The LM393 does not have built-in hysteresis, but many YL-105 modules add a small positive feedback resistor. Check your board; if not present, you may experience output jitter near the threshold. The datasheet often omits this, so add hysteresis in software (debouncing) or external resistors if needed.
The YL-105 is most commonly known as an adapter module for the NRF24L01 2.4GHz wireless transceiver. It is a utility component designed to simplify the connection between a microcontroller (like an Arduino) and the NRF24L01 radio module. YL-105 Datasheet Overview
The primary function of this module is to provide voltage regulation and a stable power supply for wireless communication.
Regulated Power: Includes an AMS1117 3.3V voltage regulator. This is critical because the NRF24L01 module is sensitive to voltage and operates strictly on 3.3V, while many microcontrollers provide 5V.
Dimensions & Form Factor: A compact footprint of 26 x 18.6 x 10mm and a weight of roughly 3g.
Connectivity: Features an 8-pin socket specifically for the NRF24L01 Wireless Module and a header for easy wiring to a breadboard or MCU. Expert Review & Performance
Based on its technical specifications, the YL-105 is highly recommended for DIY electronics projects for the following reasons:
Stability: Wireless transceivers often experience communication failures due to "noisy" power supplies or current spikes. The YL-105's onboard capacitor and regulator provide the stable current needed for reliable data transmission.
Ease of Use: It eliminates the need for complex voltage divider circuits or external 3.3V power sources, making it a "plug-and-play" solution for beginners.
Safety: It prevents permanent damage to the NRF24L01 module, which can occur if accidentally connected to a 5V power pin without regulation. Alternate Identification
While the adapter is the most common use of the "YL-105" name, it is occasionally associated with other products in different niche markets: Tip: For best results, use a south pole facing the sensor
Home Security: A wireless infrared motion sensor alarm model YL-105 exists, typically used in garages or sheds.
Consumer Tech: There is a YL105 mini drone designed for beginners and kids, featuring brushless motors and 8K video.

This module is a breakout board designed to simplify the use of the 8-pin nRF24L01 wireless transceiver with microcontrollers like Arduino.
Voltage Regulation: The main advantage of this board is the onboard AMS1117 3.3V regulator, which allows you to power the wireless module using a 5V supply (e.g., from an Arduino's 5V pin) instead of the strict 3.3V required by the raw nRF24L01 chip.
Pin Configuration: It breaks out the standard 2x4 header into a single-row format easier for breadboarding or wiring. VCC: 5V Input (regulated to 3.3V on-board). GND: Ground.
SPI Pins: CE, CSN, SCK, MOSI, MISO (standard SPI communication).
Stability: Often includes decoupling capacitors to provide stable power, which is critical for reducing communication errors in RF modules. 2. YL-105 Moisture/Humidity Relay Module
Alternatively, "YL-105" is frequently associated with an integrated humidity sensor and relay control module used for automated irrigation or climate control.
