About MakerFocus 2pcs NRF24L01+PA+LNA Wireless

Specifications: The 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 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 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
