MakerFocus 2pcs NRF24L01+PA+LNA Wireless Transceiver RF Transceiver Module 2.4G 1100m with Antenna in Antistatic Foam Compatible Ar duino

The nRF24L01+ is a 2.4GHz ISM band transceiverRange: 800+ meters line of sightIncludes 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).The on chip voltage regulator accepts supply voltages from 1.9 to 3.6V.The module has 5V tolerant inputs which allows for direct connection of SPI pins to the A r d u i n o.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).The module includes an Interrupt Request (IRQ) pin which can be used to wake the host microcontroller, (ex: Ar duino), from ...
