Most users seek a "better" datasheet because the NRF24L01 module is notoriously sensitive to voltage fluctuations. While the transceiver itself operates at
, the NRF24L01 data pins (CE, CSN, etc.) are , meaning they can be connected directly to an Arduino Uno's logic pins without damage.
The (often designated as the YL-105 ) is a voltage regulator and breakout adapter specifically designed for the NRF24L01 2.4GHz wireless transceiver module. It is widely used in Arduino and hobbyist electronics to solve the common issue of power instability in wireless modules. Why You Need a "Better" YL105 Datasheet yl105 datasheet better
pin due to insufficient current or electrical noise. The YL105 acts as a bridge, allowing you to use a stable input to provide clean power to the module.
When comparing the YL105 adapter to a direct connection, the advantages are clear: : Standard Arduino pins often provide only . The YL105 leverages the rail to provide up to Most users seek a "better" datasheet because the
The YL105 is not just a socket; it contains a dedicated (or equivalent) Low Dropout (LDO) regulator. Input Voltage Range : DC (Recommended from Arduino/USB). Output Voltage : DC (Stable output for NRF24L01). Maximum Output Current : Typically up to (Far exceeding the NRF24L01’s peak consumption of Onboard Components : Filter Capacitors : Usually includes capacitors to smooth out high-frequency noise. Power LED : Red LED indicator to confirm power input. Interface : Input : 2-pin header for VCCcap V sub cap C cap C end-sub GNDcap G cap N cap D Output : 8-pin female header for the NRF24L01 module. Wiring Diagram & Pinout
: If you still experience poor range even with the YL105, ensure your antennas are not obstructed and that you are using a High PSRR Regulator setup if the environment is electrically noisy. It is widely used in Arduino and hobbyist
The YL105 passes the SPI data lines directly through to the Arduino while regulating the power lines.

: If the red Power LED is not lit, verify that your input voltage is at least
: Wireless modules are sensitive to EMI. The onboard bypass capacitors on the YL105 serve as a "better" solution than manual wiring with loose electrolytic capacitors.
