NRF24L01 Mini Power-Enhanced 2.4G Wireless Transceiver Module

Mini power-enhanced version of the NRF24L01 2.4 GHz transceiver, for wireless data links between microcontrollers: DIY Arduino radio controls, telemetry links, sensor nodes and robotics. The boosted output extends range over the basic board while keeping a compact footprint.

Key features

• 2.4 GHz transceiver that both sends and receives, so one module type covers both ends of a link
• SPI interface for Arduino, ESP32, STM32 and Raspberry Pi boards
• 1.9–3.6 V supply: run it from a 3.3 V rail, not 5 V
• Mini board for tight enclosures and small airframes

Specifications

• Frequency: 2.4 GHz
• Supply voltage: 1.9–3.6 V
• Interface: SPI
• Operating temperature: -40 °C to +85 °C (typical)

The power-enhanced board draws more current when transmitting, so add a 10 µF capacitor across VCC and GND if the link drops out on a weak 3.3 V regulator. Pair it with another NRF24L01 module at the far end; the RF24 library for Arduino handles the setup.
