Yl105 Datasheet Better [top] -

A full manual (10 pages) is available from Yi Lin, covering settings, connections, and technical data.

The YL-105 (frequently cross-referenced as the HW-200 breakout adapter ) functions as an intermediate power conditioner and pin-out mapping shield. By bridging the massive power gap between standard 5V microcontrollers like the Arduino Uno or Mega and 3.3V RF chips, it serves as a critical single-point voltage buffer. Official Specification Value Technical Relevance 5.0V DC to 7.0V DC Max Safe to power from standard USB rails or 5V MCU pins. Output Voltage 1.9V DC to 3.6V DC (Nominal 3.3V) yl105 datasheet better

Used for monitoring water quality in industrial or municipal settings. 0 to 20 mg/L. Output Signal: 4-20mA or RS485 (Modbus-RTU). Operating Voltage: 12 to 24V DC. Protection Rating: IP68 (waterproof for immersion). Material: PC and stainless steel shell. Accuracy: ±1% Full Scale. Alpha Wire FIT-221-YL105 (Heat Shrink) Go to product viewer dialog for this item.

The YL‑105 adapter breaks out the nRF24L01’s 2×4 pin header into two standard 1×8 male headers. The pins are clearly labelled on the board. Official Specification Value Technical Relevance 5

Because the term “YL‑105” does not refer to a single component, you must identify you have before consulting a datasheet. This guide covers the most common variants separately, so you can find the information that matches your device.

├── Is it for water quality measurement? │ ├── YES → Choose SRWQ100-YL-105 chlorine sensor │ │ ├── Need 4–20mA + RS485? → Check L-com variant │ │ └── Need low-cost alternative? → First Sensor FST100-YL-105 │ │ │ └── NO → Continue to next question. │ ├── Is it for home security/motion detection? │ ├── YES → Choose YL-105 PIR alarm system │ │ ├── Battery-powered flexibility → AC/DC version │ │ └── Max coverage needed → 8-meter detection range │ │ │ └── NO → Continue to next question. │ └── Is it for cable management / wire protection? ├── YES → Choose Alpha Wire F221* YL105 tubing │ ├── Need 2:1 shrink ratio → F2211/2 or F221V1IN │ └── Need tighter 2.5:1 ratio → F3003/4 series │ └── NO → Re-evaluate search terms (YL-105 may not match your need).
