: While the power is regulated, the SPI data lines (CE, CSN, SCK, MOSI) on the nRF24L01+ are generally 5V tolerant, making this board a bridge between 5V logic and 3.3V power.
female header pins of the wireless module into a single row of breadboard-friendly male pins. This mechanical configuration eliminates messy point-to-point wiring connections, lowering the risk of parasitic resistance or intermittent contact failure. Implementation and Pin Architecture
| Variant | Typical source | How to find the datasheet | |---------|----------------|---------------------------| | nRF24L01 adapter | Electronics components sellers (e.g., Tech Sul, Proesi, Electrochip) | Use the product description; the vendor often lists specifications. For schematic details, measure the board and trace the circuit—no official document exists. | | PIR motion alarm | Security equipment distributors, wholesale platforms (Made‑in‑China, Yiwugo) | Look for user manuals under the brands . Many include a multi‑page installation and operation guide. | | Pressure switch | HVAC suppliers, Yi Lin distributors | Download the YL‑1132A pressure switch manual; it contains data for the YL‑105 series. | | Network meter | Industrial automation suppliers (Hi1718, etc.) | Contact the seller directly for the technical datasheet, as it is rarely published online. |
The YL‑105 model is also widely used for a . This is a complete security system: a main unit with an infrared sensor and a 105 dB siren, plus two remote controls. Several brands (Yilin, Verk, APT, Platinium) sell this product under the same YL‑105 model number. yl105 datasheet better
When engineers search for a "better" datasheet, they are looking for comprehensive technical data, operational limitations, and clear installation guidance. The SRWQ100-YL105-9001 datasheet provides exactly that. Here is what makes it superior: 1. Robust Technical Specifications
After reading this deep dive into the analysis, ask yourself:
A comprehensive breakdown of the typical YL-105 Specification Sheet highlights how the adapter structures clean energy for the radio frequency (RF) environment: Specification Details Impact on System Pulls power directly from 5V source rails. Output Voltage 1.9V to 3.6V DC (Regulated 3.3V typical) Provides a stable baseline for the RF transceiver. On-Board Linear Regulator AMS1117-3.3 Low Dropout (LDO) Chip Suppresses input noise and voltage fluctuations. Form Factor / Pin Count 8-Pin Female Header Socket Matches standard 2x4 dual-row pin layouts. Filtering Hardware Built-in SMD Bypass Electrolytic Capacitors Smooths peak current draws to prevent system reset. Technical Advantages of Deploying a YL-105 Board : While the power is regulated, the SPI
| Problem | Most likely cause | Solution | |---------|------------------|----------| | nRF24L01 not detected ( radio.begin() returns false) | Insufficient power to the radio module | Use the YL‑105 adapter with an that can source >500 mA | | Unreliable communication or intermittent data | Power supply noise or inadequate decoupling | Add a 100 µF electrolytic capacitor between VCC and GND close to the adapter | | Radio works but range is poor | Operating in a noisy 2.4 GHz environment | Change the radio channel in software | | No communication with Arduino Nano Every | The YL‑105 adapter works but the radio module may be faulty or incorrectly wired | Test with another nRF24L01 module and an Arduino Uno first |
The is a breakout and voltage regulation module designed specifically for the widely used NRF24L01 2.4GHz wireless transceiver . The core purpose of the YL-105 is to bridge the electrical gap between standard 5V microcontrollers and the stricter 3.3V power requirements of the radio frequency (RF) transceiver.
The YL105 datasheet reveals a sensor that is better for 80% of hobbyist and commercial indoor projects . It is robust, forgiving, and cheap. When paired with proper timing code and a clean power supply, it rivals sensors twice its price. Implementation and Pin Architecture | Variant | Typical
