KEHIPI 3pcs NRF24L01+PA+LNA 2.4G 1100m SMA Antenna Development Board
Three 2.4 GHz transceiver modules with power amplifiers and SMA antennas for 1100 m line-of-sight range and SPI control
- 3-pack gives spare modules for multi-node projects
- 4 GHz ISM band with 125 selectable channels avoids interference
- 800 m line-of-sight range with SMA antenna extends coverage
- 5 V tolerant SPI pins connect directly to Arduino
- Three data rates from 250 kbps to 2 Mbps suit different throughput needs
KEHIPI 3pcs NRF24L01+PA+LNA Development Board
This pack contains three 2.4 GHz wireless transceiver modules with integrated power amplifier and low-noise amplifier. Each board includes an SMA antenna connector for extended range. The modules operate on the ISM band and communicate via SPI with host microcontrollers such as Arduino or Raspberry Pi.
Suits makers building long-range sensor networks
Developers creating wireless peripherals, remote controls or home automation nodes benefit from the 1100 metre line-of-sight range and 125 selectable channels. Projects requiring Bluetooth, Wi-Fi or mesh networking protocols should look elsewhere as this module uses a proprietary 2.4 GHz protocol only.
3.6 V maximum operating voltage decides
The module runs from 3 V to 3.6 V and draws up to 115 mA during transmission. Any 5 V logic rail must be level-shifted before connecting to the SPI pins despite 5 V tolerant inputs. Supplying more than 3.6 V will damage the device.

Jautājumi par šo preci
Should I buy the single module or the 3-piece pack for my project?
The listing includes three NRF24L01+PA+LNA modules and three SMA antennas, giving you spare units for multiple nodes or prototypes.
What does the 1100-metre range claim mean when the board is inside a real device?
The 800-plus metres line-of-sight figure assumes clear air; walls, enclosures and nearby 2.4 GHz traffic will reduce practical distance considerably.
Which SPI settings does the 2.4 GHz transceiver support and what throughput can I expect?
The module offers 125 selectable channels and data rates of 250 kbps, 1 Mbps or 2 Mbps over a 4-pin SPI link.
