4-Pack Wireless Modules with Antenna for Long-Range Communication 1100m

If you want to enhance your wireless communication system af ably, this Wireless Transceiver module is an excellent choice. It provides a reliable balance between performance and cost. It can be easily integrated with your own MCU/ARM/PIC/AVR/STM32 system. This NRF24L01+ module features a built-in power amplifier and SMA antenna, supporting wireless communication of up to 800 meters in line-of-sight conditions. 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 channel frequency (125 selectable channels), output power, and data rate (250 kbps, 1 Mbps, and 2 Mbps). The on-chip voltage regulator supports supply voltages from 1.9 V to 3.6 V. The module has 5V tolerant inputs, allowing direct connection of SPI pins to compatible controllers, including those used with Arduino. Internal filtering helps meet RF regulatory standards. The radio uses Gaussian Frequency-Shift Keying (GFSK) modulation and fast Automatic Gain Control (AGC). The module includes an Interrupt Request pin that can wake the host microcontroller (e.g., for use with Arduino) from sleep mode upon receiving a transmission, enhancing energy efficiency in battery-powered devices. Range: Up to 800+ meters (line of sight) Frequency: 2.4 GHz – 2.5 GHz Working Voltage: 3.0 – 3.6 V Maximum Current: 115 mA Channels: 125 selectable frequencies Color: Black Material: PCB, plastic, metal Package Contents: 4 x Wireless Module 4 x Antenna 4 x NRF24L01 Wireless Module Breakout Adapter Note: The package includes only the items listed above. Other products are not included. Slight color variations may occur due to lighting and display differences. Measurement error allowance: ±1–3 cm.
