nRF24L01 module:
Specification
nRF24L01 is a single chip radio transceiver for the world wide 2.4 - 2.5 GHz ISM band.
The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator and
Enhanced ShockBurst, protocol engine.
Output power, frequency channels, and protocol setup are easily.
programmable through a SPI interface. Current consumption is very low, only 9.0mA at an output power of -6dBm and 12.3mA in RX mode.
Built-in Power Down and Standby modes makes power saving easily realizable.
Maximum operating speeds up to 2Mbps, GFSK modulation efficiency, Anti-interference ability, Particularly suitable for industrial control
NRF24L01+PA+LNA Wireless Transceiver RF Transceiver Module:
Range: 800+ meters line of sight
Includes on board support components and the RFX2401C which is the PA (Power Amplifier) and LNA (Low-Noise Amplifier)
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).
