Yl105 Datasheet Review

1. General Description

The YL-105 is a low-cost, low-power wireless transceiver module designed for various short-range wireless applications. It is based on the A7105 RF chip by AMICCOM. It operates in the 2.4GHz ISM band (Industrial, Scientific, and Medical frequency band).

5. Limitations and Engineering Constraints

While cost-effective, the YL-105 has distinct limitations that engineers must account for: yl105 datasheet

That night, they tested it. The laser beam broke. The alarm stayed silent. Then a pigeon flew past the loading dock, its shadow triggering the YL105’s rapid 15 µs response—the exact spec from the datasheet’s switching time table. Non-contact magnetic sensing – No moving parts, high

Based on technical datasheets and product listings, is a specific color and packaging suffix used by Alpha Wire FIT-221 series of heat shrink tubing. It typically indicates a The heat hit the polyolefin

Ease of Wiring: It converts the module's 2x4 (8-pin) header into a breadboard-friendly single-row header with clearly labeled pins. 3. Pinout and Connections

5. Key Features from the YL105 Datasheet

• Non-contact magnetic sensing – No moving parts, high reliability.
• Digital output – Direct interface with microcontrollers (Arduino, STM32, ESP32, Raspberry Pi).
• Adjustable sensitivity – Onboard potentiometer for setting trigger distance.
• Power indicator – Shows module is powered.
• Response frequency – Up to 100 kHz (suitable for RPM measurement on small motors).
• Reverse polarity protection – On better modules.

The heat hit the polyolefin. The yellow sleeve didn't just melt; it tightened with mechanical precision, gripping the cable in a flame-retardant, fluid-resistant embrace. Within seconds, the frayed danger was entombed in a semi-rigid, yellow shell.
