Yl105 Datasheet — Better

: Clear labeling of VCC, GND, and data pins to prevent short circuits.

The nRF24L01 and nRF24L01+PA+LNA modules require a . Many Arduino boards (like the Uno or Nano) have a 3.3 V output, but that output often cannot supply enough current for reliable operation, especially when the radio transmits at high power. Moreover, the nRF24L01’s 2×4 pin header is physically awkward to breadboard. The YL‑105 adapter fixes both issues.

It is designed to be a "cable replacement." This means that whatever data you send into the module via Serial TX/RX pins comes out of the other module's Serial pins. This makes it incredibly easy to use because it requires no complex wireless protocols—you just treat it like a direct serial connection. yl105 datasheet better

The YL‑105 adapter board is designed to make it easier and safer to use 2.4 GHz wireless transceiver modules with Arduino and other microcontrollers. It solves two major problems that plague nRF24L01‑based projects.

Serial.print("Moisture analog: "); Serial.println(moisture); Serial.print("Digital wet status: "); Serial.println(wetDetected == LOW ? "WET" : "DRY"); : Clear labeling of VCC, GND, and data

: Lower internal resistance minimizes conduction losses. Your system wastes less power as heat during high-current operations. Moreover, the nRF24L01’s 2×4 pin header is physically

Firmly press the 8-pin female header of the nRF24L01+ into the matching dual-row socket on top of the YL-105.

Connect the remaining SPI pins to the corresponding hardware SPI pins of your specific controller (e.g., Pins 11, 12, and 13 on an Arduino Uno).

The search for "YL-105" datasheets reveals at least three distinct product categories sharing this designation: precision water quality sensors, security motion alarms, and industrial heat shrink tubing. Each serves completely different applications, yet all carry the YL-105 model number. Understanding which one you need is the first step to success.
