(often styled as YL105) typically refers to a specific breakout board adapter designed for the nRF24L01+ wireless transceiver module
In industrial water monitoring, "YL105" may also refer to the FST100-YL105 , a digital Residual Chlorine Sensor
For advanced technical details, you can find the Alpha Wire YL105 Specification Sheet on DigiKey or the L-com SRWQ100-YL105 Sensor Data via Octopart. yl105 datasheet better
: Digital input pin used to transition the radio between standby, receive, and transmit modes.
: Standards like UL 224, CSA, or RoHS compliance for industrial applications. (often styled as YL105) typically refers to a
In the crowded world of capacitive humidity sensors, the YL105 is often misunderstood. Viewed by beginners as a "cheap alternative," this sensor module—when paired with a correct reading of its datasheet—offers a superior price-to-performance ratio for 80% of DIY and commercial IoT projects.

The YL-105 board simplifies power management for the nRF24L01, which is notorious for being sensitive to power fluctuations. Arduino Forum Input Voltage : 5V DC (typically from an Arduino 5V pin). Output Voltage : 1.9V to 3.6V DC (regulated by an onboard AMS1117-3.3 Operating Current : Approximately 12.3 mA during active RX mode. Compatibility : Designed for 8-pin nRF24L01+ modules. Protection
Unfiltered high-frequency power rails introduce electronic noise into the RF synthesizer stage of the transceiver. This noise distorts the 2.4GHz carrier wave, reducing the effective range and increasing packet error rates. Providing a dedicated, ripple-free linear power supply through the adapter helps the module achieve its maximum rated transmission distance. Simplifies Rapid Prototyping
: Cheap nRF24L01 modules often suffer from power noise. While the YL-105 includes some filtering, adding a
Integrating 2.4GHz RF transceivers into 5V development environments often leads to unexpected hardware behaviors. Utilizing the YL-105 datasheet addresses three critical failure vectors: 1. Inadequate 3.3V Current Supply from Microcontrollers
