Yl105 Datasheet

The datasheet details for the YL-105 adapter board usually include: Input Voltage: 5V DC (can be powered directly from an Arduino's 5V pin). On-board Regulator:

Using an nRF24L01+ directly connected to an Arduino's onboard 3.3V power pin often results in intermittent packet loss, transmission timeouts, or outright data corruption due to inadequate current spikes during RF broadcasting. The YL-105 acts as a dedicated voltage translation and power filtering hub to achieve reliable 2.4GHz wireless communication. 📋 Technical Specifications Overview Operational Rating 5.0V DC (Highly recommended for stability) Output Voltage Range ( VOUTcap V sub cap O cap U cap T end-sub ) 1.9V to 3.6V DC (Regulated 3.3V typical output) Core Linear Regulator IC Advanced Monolithic Systems AMS1117-3.3 Maximum Output Current Up to 800 mA (Provides massive headroom for PA/LNA modules) Quiescent Current Consumption ~12.3 mA (Internal consumption under nominal load) Compatible Transceiver Footprint Dual-row 8-pin (2x4) standard male/female header Physical Dimensions 26mm x 19mm x 12mm 🛠️ Pinout Configuration & Architectural Design

Often used for manual override or left unconnected. VSS: Common return path. Common Applications

Optional, active-low notification pin from the radio to host MCU. 🔬 Circuit Architecture & Component Breakdown yl105 datasheet

Pass-through logic pin. Acts as the active-low SPI peripheral select pin. Pass-Through Signal Interface

Wireless transmissions can cause sudden current spikes. The onboard voltage regulator and filtering capacitors provide a stable current, preventing random disconnections or module resets. Technical Specifications & Parameters
