Specification: nRF24L01+ is a 2.4GHz ISM band transceiver 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) 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 Ar duino 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 sleep when the module receives a transmission providing great power conservation in battery devices Auto-acknowledge and auto-retransmit abilities Weight: 13.28 g (0.468 oz) Board dimensions, excluding pins: 15.5mm (0.61/) width x 40.7mm (1.6/) length x 12.2mm (0.48/) height Dimensions of antenna, when angled at 90 degrees: 87mm (3.43/) height x 9.5mm (0.37/) diameter Package Including: 2 * Wireless Module 2 * Antenna
