Yl105 Datasheet Better

The YL-105 (also known as YL105) is a popular 5V to 3.3V VCC Adapter Board specifically designed for the nRF24L01+ wireless module. It solves the common issue where microcontrollers like the Arduino Uno (5V) cannot directly power the nRF24L01+ (3.3V) reliably due to current spikes.  Technical Specifications

Key Note on Voltage: While many YL-105 boards accept 5V on VCC, the data pins (TX/RX) are often 3.3V logic. If you are using a 5V Arduino (Uno/Nano), it is safest to use a logic level converter or a voltage divider on the RX pin of the module to prevent damage. The YL-105 (also known as YL105) is a popular 5V to 3
