Built-in power management and indicator On-board SMD power LED for quick visual confirmation of power. Integrated 3.3V voltage regulator accepts a +5V supply and provides a stable 3.3V rail for the connected nRF24L01+ module, eliminating the need for a separate regulator when powering from 5V systems. High-performance wireless transceiver Uses the nRF24L01+ chip with added PA (power amplifier) and LNA (low-noise amplifier), RF switches and bandpass filtering to improve signal sensitivity and extend effective communication distance. Operates in the 2.4 GHz ISM band for global, licence-free use. Robust communication features Supports automatic acknowledgment (ACK) and automatic retransmission for reliable packet delivery. Supports up to six data reception channels (data pipes), enabling multiple logical links or multi-node topologies on the same module. Easy interfacing and compatibility 5V-tolerant inputs allow direct connection of SPI pins from 5V microcontrollers without level shifters. Standard SPI interface makes the module compatible with common development platforms that support SPI (for example Arduino, STM32, Raspberry Pi and other microcontrollers). What this product solves Simplifies wireless connectivity for small embedded projects by integrating power regulation and a ready-to-use RF front end. Reduces wiring and component count compared to using a separate nRF24L01+ module plus an external regulator and filtering. Improves link range and reliability over a plain transceiver module thanks to added PA, LNA and RF filtering. Key attributes Function: 2.4 GHz transceiver with built-in regulator and power indicator. Compatibility: Direct SPI connection; 5V-tolerant inputs; supplies 3.3V to nRF24L01+. Performance: Enhanced RF chain (PA/LNA/filters) for longer range and better signal quality. Size/format: Compact module with surface-mounted indicator suitable for breadboard or PCB integration. Use scenarios Wireless sensor networks: Connect multiple battery- or USB-powered sensors to a central hub. The built-in regulator and 5V tolerance allow simple wiring to typical microcontroller boards, while automatic ACK and retries improve data reliability. Remote control and telemetry: Use the module for RC controls, telemetry links, or remote switches where extended range and stable links are required; PA and LNA improve communication distance. Microcontroller-to-microcontroller links: Establish low-latency SPI-based wireless links between Arduino, STM32 or Raspberry Pi projects for data exchange, remote I/O, or distributed control without extra level shifting or external regulators.
