Yl105 Datasheet -

Because the YL105 is not an official semiconductor part but a module assembled from standard components, no single PDF exists from a major brand like Texas Instruments or STMicroelectronics. However, you can obtain equivalent technical data from:

Controlling multi-speed settings or sleep timers. yl105 datasheet

Possible causes: (1) No pull-up resistor on DO; (2) Potentiometer set too sensitive; (3) Sensor damaged by reverse voltage; (4) Wrong magnetic pole used. Because the YL105 is not an official semiconductor

The is an adapter breakout board specifically designed for the nRF24L01+ 2.4GHz wireless transceiver module . Its primary function is to resolve common power supply and wiring issues encountered when interfacing these wireless modules with 5V microcontrollers like the Arduino Uno. 1.
