When choosing a LoRaWAN gateway, it is important to consider your specific network needs. LoRaWAN gateways are divided into two main categories based on the number of channels they address: single-channel gateways and multi-channel gateways.
Multi-channel gateways can receive multiple wireless channels and spreading factors simultaneously, making them more suitable for complex and scalable projects.
Single-channel gateways are cheaper and more suitable for limited network needs because they can only receive wireless signals from a specific radio channel with a specific spreading factor at a time.
If you only need a single-channel gateway and don't want to spend too much money, the following devices can be used as LoRa gateways. They can all be used as IoT gateways to connect various devices, have rich GPIO and general interfaces, and can connect various sensors and actuators.
You can build a single-channel LoRaWAN gateway using a Raspberry Pi and LoRa shield to report sensor data to a remote location. In this gateway, the Raspberry Pi acts as a receiver/client, while the LoRa shield acts as a transmitter/server.
LattePanda 3 Delta is an x86 SBC with an Intel Core N5105 dual-core processor that can run Windows 10 and Linux. It can be used as a LoRaWAN gateway to send sensor data to the cloud.

You can configure LoRaWAN devices in the Arduino Cloud, register for The Things Console account, create a simple test program to view data from the device, and send data from the Arduino Cloud to the device.
BeagleBone Black Wireless single-board Linux computers can be used in conjunction with Long Range (LoRa) transceivers to send and receive messages in a mesh network, with one transmission/reception node acting as a relay in the system.

Intel Edison can be connected to LoRaWAN by adding a LoraWAN module. The Intel Edison can also be connected to WiFi by adding a WiFi module. This makes Intel Edison a very flexible IoT gateway that can connect to a variety of devices and protocols.
