NRF24L01 Module Without an Antenna

The NRF24L01 module without an antenna is a low-cost, low-power, 2.4 GHz wireless transceiver module designed for short-range wireless communication. It is based on the Nordic Semiconductor nRF24L01 chip and operates on the 2.4 GHz ISM (Industrial, Scientific, and Medical) band.

Features:

• Operating Voltage: 1.9V – 3.6V (Typically powered with 3.3V)
• Communication Interface: SPI (Serial Peripheral Interface)
• Data Rate: 250kbps, 1Mbps, 2Mbps (Selectable)
• Operating Frequency: 2.4GHz – 2.525GHz (125 Selectable Channels)
• Output Power: Adjustable (-18 dBm to 0 dBm)
• Current Consumption:
  • Transmission Mode: ~11mA (at 0 dBm)
  • Receive Mode: ~13.5mA
  • Power Down Mode: 900nA
• Range: ~50 to 100 meters (Line of Sight, Indoors)
• Packet Size: 1 to 32 Bytes
• Address Width: 3 to 5 Bytes
• Error Detection: CRC (Cyclic Redundancy Check)
• No External Antenna: It uses an onboard PCB trace antenna.
