Philippines

Features:
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).
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).
On chip voltage regulator accepts supply voltages from 1.9 to 3.6V.
V tolerant inputs, allows for direct connection of SPI pins to the Arduino.
Internal filtering results in high margins of meeting RF regulatory standards.
Radio uses Gaussian Frequency-Shift Keying (GFSK) modulation as well as fast Automatic Gain Control (AGC).
Includes an Interrupt Request (IRQ) pin which can be used to wake the host microcontroller, (ex: Arduino), from sleep when the module receives a transmission providing great power conservation in battery devices.
Auto-acknowledge and auto-retransmit function.
