NRF24L01 is a 2.4GHz ISM band transceiver. This transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator and enhanced Shock Burst, protocol engine.
A host microcontroller can communicate and configure the nRF24L01+ over a 4-pin Serial Peripheral Interface (SPI). The configuration registers are accessible through the SPI connection.
Configurable parameters include frequency channel (125 selectable channels), output power, and data rate (data rates: 250kbps, 1Mbps, and 2Mbps).
The module has 5V tolerant inputs which allows direct connection of SPI pins.
Internal filtering results in high margins of meeting RF regulatory standards. The module’s radio uses Gaussian Frequency-Shift Keying (GFSK) modulation as well as fast Automatic Gain Control (AGC)
