Short Range RF

nRF24L01+ 2.4GHz radio transceiver module allows for easy and low-cost short ranged wireless communication. Compatible with Arduino microcontrollers using SPI and useful in projects such as game controllers, wireless peripherals and RC vehicles.

Features:

• Worldwide 2.4GHz ISM band operation
• Modulation format: GFSK
  
• Communication up to 30m with clear line of sight
• 125 configurable frequency channels
• Data rates: 250kbps, 1Mbps, 2Mbps

Pinout:

• VCC: Supply voltage of 1.9-3.6V (other pins can tolerate 5V)
• GND: Ground
  
• CE: Chip Enable - sets module to receive or transmit mode
• CSN: Chip Select Not - an active-LOW pin and is normally kept HIGH. When this pin goes low, the module begins listening on its SPI port for data and processes it accordingly.
• IRQ: Interrupt pin - can optionally alert when new data is available to process
• SCK: Serial Clock for SPI
• MOSI: Master Out Slave In for SPI input to module
• MISO: Master In Slave Out for SPI output from module
