RAK7285/RAK7285C WisGate Edge Ultra Datasheet
Overview
Descriptions
RAK7285 WisGate Edge Ultra is the latest version of the RAK WisGate Edge series, designed to overcome the limitations of half-duplex communication. It's tailored to meet the demands of high-density network deployments, particularly for smart city infrastructure, metering applications, and other scenarios requiring reliable two-way communication at scale.
This gateway supports up to 8 LoRa channels in full-duplex (a 16-channel variant is coming soon), with multi-backhaul options including Ethernet, Wi-Fi, and Cellular connectivity. Its integrated advanced cavity diplexers not only provide exceptional out-of-band interference suppression but also provide lightning protection for the LoRa antennas, ensuring uninterrupted and secure full-duplex communication.
In addition, RAK7285 operates under WisGateOS2, which is built on the latest OpenWrt kernel. The OS Web UI features a new design and supports multiple extension installations, enabling remote management using WisDM for personalized gateway customization.

Hardware
The hardware specification covers the interfacing of the RAK7285/RAK7285C and its corresponding functionalities. It also presents the parameters and the standard values of the board.
Interfaces
- The SD card in the SD card slot must not be ejected. Doing so might affect the device's performance, as various logs and data are stored on it.
- The SIM card slot of the cellular versions is not hot-swappable. Ensure the gateway is switched off before inserting or ejecting the SIM card.
- The available antenna interfaces vary between variants. For example, two N-type LTE interfaces are available on the RAK7285C, but not on the RAK7285.
Reset Key Functions
The functions of the Reset key are as follows:
- Short press: Restart the gateway.
- Long press (5 seconds or more): Restore factory settings.
