If you want to set up your wireless communication system with low cost, this wireless Transceiver module is the most suitable module to choose!
It can achieve a good balance between wireless transition performance and cost! You can easily add it with your own MCU/ARM/PIC/AVR/STM32 system!
What's more, this NRF24L01+ module is designed with Power amplifier and SMA antenna This allowed you to use the wireless communication up to 800+ meters! (No barrier)
The Aokin 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.
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 Arduino.
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: Arduino), from sleep when the module receives a transmission providing great power conservation in battery devices.
