Micro NRF24L01+ Power Enhanced 2.4GHz RF Transceiver Module

In open, line-of-sight conditions with proper antennas, the module can achieve ranges up to approximately 250 meters. The actual range is highly dependent on antenna selection, environmental interference, and data rate settings. The integrated power amplifier provides a +7dBm output, significantly improving link budget over standard versions.

The module communicates via a standard 4-wire SPI interface (CSN, SCK, MOSI, MISO). You will need to connect these pins to available SPI ports on your flight controller and provide a stable 3.3V power supply. Software libraries like RF24 are commonly used to handle the protocol, requiring custom coding on the flight controller and ground station to implement your specific telemetry or control scheme.

Yes, the module's I/O pins are 5V tolerant, meaning they can safely receive signals from a 5V logic device. However, the module itself must be powered strictly between 1.9V and 3.6V, typically 3.3V. When using a 5V Arduino, you must use a separate 3.3V regulator for the module's VCC and ensure the Arduino's logic pins are configured for 5V output.

The module features ultra-low power consumption. In active transmission mode at +7dBm output, current draw is typically around 11.5mA. In active receive mode, it draws approximately 12.5mA. It supports power-down and standby modes which reduce current to the microamp range, making it suitable for battery-powered drone applications where power management is critical.
