NRF Module

Communication Protocol:

• Wireless: Operates in the 2.4 GHz ISM band.
• Modulation Scheme: GFSK (Gaussian Frequency Shift Keying).

Operating Frequency Range:

• 2400 MHz to 2525 MHz.

Data Rates:

• 1 Mbps (default), 2 Mbps (high-speed mode), and 250 kbps (low-power mode).

Transmission Power:

• Adjustable output power:
  • -18 dBm (lowest power),
  • 0 dBm,
  • +6 dBm,
  • +10 dBm (maximum power).

Receiver Sensitivity:

• -94 dBm at 1 Mbps (standard mode).

Range:

• Typical range: 50 meters in open space (can reach up to 100 meters with higher transmit power and optimal conditions).

Power Supply:
