If you are developing with Arduino, look for the "A7105" library or libraries related to the "FlySky" protocol (as the A7105 is the chip used in many FlySky RC transmitters).
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: yl105 datasheet
Since YL105 is a generic module name, no single "official" PDF exists. Use this guide along with the datasheet of the actual Hall IC on your module (e.g., AH3144, SS441A, or OH137). If you are developing with Arduino, look for
Many sellers offer the YL105 as a that includes the bare Hall sensor chip, a comparator (like LM393), a potentiometer for threshold adjustment, an LED indicator, and pull-up resistors. The bare sensor's raw datasheet is often referenced simply as "YL105" or identified by its actual IC marking (e.g., OH137, AH3144, or similar). Use this guide along with the datasheet of
