The YL-105 is a compact electromagnetic relay that is used to control the flow of electrical current in industrial control systems, power supplies, and other applications.
This is the most common configuration – active low. Check your specific module for an output LED indicator; when the LED lights up, the output is active (usually LOW).
If you experience erratic wireless behavior, adding a yl-105 datasheet
While the nRF24L01+ signal pins are 5V tolerant, its VCC power input cannot handle more than 3.6V. Attempting to power the transceiver directly from a 5V microcontroller rail like an Arduino Uno will instantly destroy the RF chip. The YL-105 acts as a protective interface by integrating a and decoupled bypass capacitors to guarantee clean, stable power delivery. Key Technical Specifications Specification Details Input Voltage (VCC) 4.8V to 12V DC (Recommended: 5V) Output Voltage 3.3V DC (Regulated) On-board Voltage Regulator IC AMS1117-3.3 Linear Regulator Compatible Transceivers Standard 8-Pin nRF24L01+ / nRF24L01+PA+LNA Target Logic Voltage 3.3V (Inputs are 5V tolerant) On-board Indicators SMD Power LED Module Dimensions 26mm x 19mm x 12mm Detailed Pinout Configuration
If you are looking for specific pressure ranges or output types (e.g., 4-20mA vs 0-10V), I can provide a more tailored selection of models. Model A-105 Pressure Transducer Datasheet The YL-105 is a compact electromagnetic relay that
: A small surface-mount current-limiting resistor is placed in series with an SMD LED to visually verify that input power is active. Hardware Hookup and Microcontroller Implementation
These pass directly through to the nRF24L01. Why Use It? If you experience erratic wireless behavior, adding a
