The WisGate Developer D4 (RAK7244) is a successor of WisGate Developer D3 (RAK7243). This device consists of a Raspberry Pi 4, a RAK2245 Pi HAT, which includes a GPS module and a Heat Sink for better performance and thermal heat dissipation management, and an optional RAK2013 Cellular Pi HAT. Its housing is entirely built from aluminum.

The built-in RAK2245 Pi HAT uses the SX1301 RF front-end chip from Semtech, which is a powerful LoRa digital processing engine. It is able to receive up to 8 LoRa packets simultaneously sent with different spreading factors on different channels and available in multiple variants so it can be used for all LoRa Alliance frequency bands. This unique capability allows for innovative network architectures to be implemented, which is advantageous over other short-range systems. The built-in RAK2013 Cellular Pi HAT is based on the EG95 from Quectel, which is an LTE CAT4 module optimized specifically for M2M and IoT applications.

WisGate Developer D4 is a Class A and C compliant that is ideal for prototyping, proof-of-concept demonstrations or for the evaluation of future deployment scenarios. It includes a ready to use Firmware based on Raspbian OS, which makes it possible to connect the Gateway to any standard LoRaWAN Server. It is developer-friendly as the large Raspbian OS community is a well-established one. It is especially suited to addressing a variety of applications like Smart Grids, Intelligent Farms, and other IoT Enterprise applications.

Available Modes:

WisGate Developer D4 (RAK7244) - this is the base model with the Raspberry Pi 4 (RPi 4) and the RAK2245
WisGate Developer D4+ (RAK7244C) - this is the Cellular version that includes the RPi 4, RAK2245, and the RAK2013 Cellular Pi HAT
WisGate Developer D4P (RAK7244P) this version allows for powering the gateway via PoE by adding the RAK9003 Pi HAT to the base configuration (RPi 4 + RAK2245 + RAK9003)
