iubfegt 4Pcs NRF24L01+P LNA Wireless Module with Antenna 1100 Meters Long Distance with NRF24L01 Wireless Module Adapter 3.3V

If you want to make 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! A host microcontroller can communicate and configure the nRF24L01+ over a 4-pin Serial Peripheral Interface (SPI). The configuration registers are accessible via the SPI connection. Configurable parameters include channel frequency (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 that allow for direct connection of SPI pins to the (compatible with) for arduinoIDE. You can easily 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 the wireless communication up to 800+ meters! (No barrier) Internal filtering results in high margins of meeting regulatory standards. The module radio uses Gauss Frequency-Shift Keying (GFSK) modulation as well as fast Automatic Gain Control (AGC).
