4pcs NRF24L01+PA+LNA Radio Modules with Antenna, 1100 Meter Range

4pcs NRF24L01+PA+LNA Radio Modules with Antenna, 1100 Meter Range Description

1. If you want to build a cost-effective wireless communication system, this wireless receiver module is the perfect choice! It strikes a great balance between wireless performance and cost! 2. You can easily build it using your own MCU/ARM/PIC/AVR/STM32 system! Furthermore, this NRF24L01+ module is equipped with a power amplifier and an SMA antenna, enabling wireless communication up to 800+ meters! (Without obstructions) 3. A host microcontroller can communicate with and configure the NRF24L01+ via a 4-pin Serial Peripheral Interface (SPI). The configuration registers are accessible through the SPI connection. Configurable parameters include the channel frequency (125 selectable channels), output power, and data rate (250 kbps, 1 Mbps, and 2 Mbps). 4. The integrated voltage regulator accepts supply voltages from 1.9 to 3.6 V. The module features 5V-tolerant inputs, allowing direct connection of the SPI pins to (compatible with) Arduino IDE. Internal filtering results in high margins for compliance with radio standards. The module's radio uses Gaussian Frequency Shift Keying (GFSK) modulation and fast automatic gain control (AGC). The module includes an interrupt request (IRQ) pin, which can be used to wake the host microcontroller (e.g., for Arduino IDE) from sleep mode when the module receives a message, enabling significant power savings in battery-powered devices. 7.
