Yl105 Datasheet //free\\ Jun 2026

AMS1117-3.3V (steps down 5V to the 3.3V required by the nRF24L01+). Output Voltage: Stable 3.3V to power the radio module. Operating Current: Typically peaks around 12–15mA during transmission. Connectivity: 2x4 female header for plugging in the nRF24L01+. Input Pins:

If powered directly by a microcontroller's native 3.3V pin, this demand often causes a temporary voltage drop (brownout), resulting in failed packet transmissions, packet loss, or unhandled chip resets. yl105 datasheet

The YL-105 is a staple in the Arduino and robotics hobbyist community. Unlike a simple magnetic switch (which only detects presence/absence), the YL-105 is a paired with a comparator to offer both analog (magnetic field strength) and digital (threshold trigger) outputs. The datasheet, typically a 1-2 page document from generic Chinese manufacturers, is sparse but covers the essentials. AMS1117-3
