Yl105 Datasheet -

The is a dedicated power regulation and interface breakout module designed specifically for the popular Nordic Semiconductor nRF24L01 2.4GHz wireless transceiver. Because the nRF24L01 module operates strictly at a 3.3V VCC limit, connecting it directly to 5V development systems like the Arduino Uno can permanently damage the radio chip. The YL-105 resolves this issue by integrating an on-board AMS1117-3.3 Low Dropout (LDO) voltage regulator and filter capacitors, ensuring a stable, noise-free 3.3V power supply from a 5V input.

The YL-105 Module: Your Essential Guide and Datasheet Breakdown

If the jumper is installed, the relay activates when IN = LOW. The wiring is identical, but logic is reversed. yl105 datasheet

For the engineer or hobbyist, the key to success with this sensor lies not in the hardware itself, but in the . By understanding the inverse relationship between voltage and clarity, and by compensating for environmental factors, the YL-105 transforms from a simple component into a sophisticated eye for water quality.

Note: Since "YL-105" is a common PCB module designation (often sold on breakout boards with an LM393 comparator), this review assumes you are referring to the (based on the 49E or similar linear Hall element). If you meant a specific IC datasheet, this review covers the typical engineering specifications of the module itself.

The is a dedicated power regulator and breakout interface engineered specifically for the highly popular Nordic Semiconductor nRF24L01+ 2.4GHz wireless transceiver modules. It solves critical power stability and pin-mapping issues commonly encountered when interfacing 3.3V RF transceivers with 5V microcontrollers like the Arduino UNO, Mega, or classic 8051 systems.
