Product Description

The nRF24L01+ Mini is engineered for reliable "point-to-point" or "star network" topologies (up to 6 receiving nodes). It features built-in CRC error detection and auto-retransmit capabilities, ensuring data integrity even in environments crowded with Wi-Fi and Bluetooth signals. Because it operates with a very low peak current (approx. 11.3mA at 0dBm), it can run for months or even years on a single coin-cell battery when used with proper sleep-mode programming. The module includes an integrated PCB trace antenna, eliminating the need for bulky external hardware.

Key Features

Ultra-Small Form Factor: Roughly half the size of a standard nRF24L01+ module, perfect for "hidden" or embedded installations.
Low Power Consumption: Features a "Power Down" mode that draws only 900nA, making it one of the most efficient RF modules available.
MultiCeiver™ Technology: Allows a single primary receiver to listen to up to six different transmitters simultaneously.
5V Tolerant Pins: While the module requires 3.3V power, the SPI data pins can be connected directly to a 5V Arduino without a level shifter.
High Data Rate: Supports up to 2 Mbps, fast enough for basic audio streaming or high-frequency sensor logging.

Technical Details

Channels: 126 selectable channels (Avoids interference with Wi-Fi).
Modulation: GFSK.
Sensitivity: -82 dBm at 2 Mbps.

Prototyping and Engineering Tips from Robogears

Power Stability is Key: The nRF24L01+ is extremely sensitive to power supply noise. Even if your 3.3V rail seems stable, we strongly recommend soldering a 10uF to 100uF electrolytic capacitor directly across the VCC and GND pins of the module. This prevents "Radio Not Found" or transmission failures caused by sudden current spikes.
The 3.3V Rule: Although the data pins are 5V tolerant, the VCC pin MUST NOT exceed 3.6V. Connecting VCC to the 5V pin of an Arduino will destroy the chip instantly.
Channel Selection: Standard Wi-Fi usually occupies lower channels. To improve reliability and range, try setting your nRF24L01+ to a higher frequency channel (e.g., radio.setChannel(115)) to move your signal away from heavy Wi-Fi traffic.
Address Management: To communicate, both the transmitter and receiver must have the exact same Pipe Address (usually a 5-byte hex value). Ensure your code defines these addresses clearly on both ends of the link.
