Arduino and NRF24L01 : 6 Steps (with Pictures) - Instructables

The YL105 is designed for 5V logic. With 3.3V microcontrollers: yl105 datasheet

The YL105 is a "workhorse" IC in the domestic appliance market. You will most likely encounter it in: Arduino and NRF24L01 : 6 Steps (with Pictures)

The datasheet typically lists quiescent current around (for the LM393 + Hall sensor). This makes it suitable for battery-powered projects if you power down the sensor between reads. yl105 datasheet

(VCC/GND), it does not shift the logic levels for the SPI data lines. Fortunately, the nRF24L01+ data pins are 5V tolerant
