4Pcs Wireless Module with Antenna for Long Range Communication 1100m Transmission Distance|RF24-Compatible Solution

If you want to make your wireless communication system with low cost, this Wireless Transceiver module is a suitable choice! It provides a good balance between wireless transmission performance and cost. You can integrate it with your own MCU/ARM/PIC/AVR/STM32 system. This NRF24L01+ module is designed with a power amplifier and SMA antenna, enabling wireless communication up to 800+ meters in line of sight (no barrier). 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 (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 direct connection of SPI pins to compatible controllers, including those used with Arduino IDE. Internal filtering results in high margins of meeting RF regulatory standards. The module radio uses Gauss Frequency-Shift Keying (GFSK) modulation and fast Automatic Gain Control. The module contains an Interrupt Request (IRQ) pin that can be used to wake the host microcontroller (e.g., for Arduino IDE) from sleep mode when a transmission is received, providing significant energy savings in battery-powered devices.
