<b>Introductions: </b><br> The Addicore nRF24L01 is a 2.4GHz ISM band transceiver. The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator and enhanced ShockBurst, protocol engine. <br> 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. <br> Configurable parameters include frequency channel (125 selectable channels), output power, and data rate (data rates: 250kbps, 1Mbps, and 2Mbps). The module has 5V tolerant inputs which allows direct connection of SPI pins. <br> 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).<br><br> <b>Specification: </b><br> Frequence: 2.4GHz~2.5GHz <br> Operating voltage: 3 ~ 3.6V Max <br> Current: 115mA <br> Multi-frequency: 125 frequency<br> Support up to six channels of data reception<br><br> <b>Package Included:</b><br> 2*NRF24L01+PA+LNA Wireless Transceiver RF Transceiver Module<br> 2*SMA Antenna
