Yl105: Datasheet
When using this board with a microcontroller like an Arduino, the connection logic is as follows: Description Power Input Connect to (the regulator handles the drop to 3.3V). Connect to common ground. Chip Enable Digital pin used to control RX/TX modes. Chip Select Not SPI Select pin (active low). Serial Clock Connect to hardware SPI clock pin. Master Out Slave In Connect to hardware SPI MOSI pin. Master In Slave Out Connect to hardware SPI MISO pin. Interrupt Request Optional pin for handling packet arrival. Usage Note While the YL-105 handles the power supply
Instead of messing with external resistors or voltage dividers, the Go to product viewer dialog for this item. provides a convenient pin socket to easily plug in the nRF24L01 module.
Extremely low (micro-ampere range in standby), making it ideal for energy-efficient "green" appliances. yl105 datasheet
The technical parameters outlined in the YL-105 module datasheet include: Specification Note / Context Can accept up to 7.0V max depending on the LDO variant. Output Voltage 1.9V to 3.6V DC Configured out-of-the-box to supply precisely 3.3V . Onboard Voltage Regulator AMS1117-3.3 IC Industry-standard LDO capable of handling up to 800mA peak. Quiescent / Operating Current 12.3 mA typical Scalable based on the underlying nRF24L01+ TX/RX state. Form Factor Dimensions 26mm x 19mm x 12mm
, meaning you can usually connect them directly to a 5V Arduino without needing additional level shifters. Instructables or a specific code library to get your communication started? When using this board with a microcontroller like
1. Input Headers (From Microcontroller / External Power Supply)
The built-in 3.3V regulators on standard development boards are often unable to supply enough current during intense wireless transmission bursts. This issue becomes especially acute when dealing with high-power modules that contain integrated Power Amplifiers (PA) and Low-Noise Amplifiers (LNA).

: Transmits configuration data from the MCU to the radio.
The YL105 is typically available in a small package, such as a SOT-23-5 or a SOP-8.
