Yl105 Datasheet Better Official

: While standard microcontroller boards offer a 3.3V output pin, their built-in regulators typically provide very low current (often limited to 50mA or less). When the nRF24L01 enters transmission mode—especially high-power variants featuring an external Power Amplifier (PA) and Low Noise Amplifier (LNA) —the instantaneous current spike creates a voltage drop. This causes the radio module to reset or fail to process the Enhanced ShockBurst protocol .

The generic nRF24L01+ module presents connections via a dense, unlabelled 2x4 dual-row header. This arrangement makes direct breadboard connection impossible and risks wiring errors. The YL-105 maps this layout cleanly into a clearly labeled, single-row pinout. Definitive YL-105 Wiring Map 5V-3.3V VCC Adapter Board for NRF24L01 Wireless Module

Unlike sensors offering only analog output, the YL-105 provides both RS485 digital communication and 4–20mA analog signals. This dual-output design means you can integrate it with legacy PLC systems using analog inputs or modern SCADA systems using MODBUS-RTU protocol. yl105 datasheet better

Route a jumper wire from the 5V pin of the MCU to the VCC pin on the YL-105. Connect the GND pins together.

To provide the best information, I have categorized the technical specifications for each below. YL-105 nRF24L01+ Adapter Module : While standard microcontroller boards offer a 3

Many engineers overlook this. The DHT11's output high voltage is 4V minimum when run at 5V—this can damage a 3.3V ESP32. The YL105 datasheet states that signal levels are TTL compatible and function reliably down to 3.3V because the onboard regulator handles the conversion.

, ensuring the module doesn't "brown out" during high-power transmission bursts. The generic nRF24L01+ module presents connections via a

The YL105 passes the SPI data lines directly through to the Arduino while regulating the power lines.

A for the YL-105 does not exist as a single document from the module maker. The professional approach is to combine the LM393 comparator datasheet , the IR phototransistor datasheet (from a known equivalent), and a reverse-engineered schematic . This yields all necessary electrical, optical, and timing specifications for reliable integration into embedded systems.
