: 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.
. The LDO regulator requires a "dropout" margin to function. yl105 datasheet better
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 : If you still experience poor range even
: Note that while the YL105 powers the module at The (often designated as the YL-105 ) is
, it often fails or resets when powered directly from an Arduino’s
, the NRF24L01 data pins (CE, CSN, etc.) are , meaning they can be connected directly to an Arduino Uno's logic pins without damage.
The YL105 passes the SPI data lines directly through to the Arduino while regulating the power lines.
