RAK7391 WisGate Connect is a Raspberry Pi CM4-based gateway product meant to support different radio and WisBlock modules. It has several interfaces to meet the needs of different developers (HDMI, Ethernet, USB, mPCIe, CSI, DSI, M.2, WisBlock, PoE, Raspberry Pi HAT). Of course, it can also be used as a basic LoRaWAN gateway product supporting up to 4 separate modules (you can have a 16-channel sub GHz LoRaWAN gateways plus a 2.4 GHz LoRaWAN gateway in the same device). It has flexible power supply modes such as DC terminal, Phoenix terminal, and POE (optional). The RAK7391 provides a fan interface to dissipate heat for the CPU that you can control based on the CPU temperature. It can monitor the power supply. In the event of a power failure, the ultracapacitors can provide power to the system, so that the system can send a notification or easily survive micro-cuts in the power supply.

Software

We have prepared a custom «distro» for the WisGate Connect called RAKPiOS. The RAKPiOS is a fork of the Raspberry Pi OS with all the required drivers to use the device, some security changes, helper scripts and Docker included by default.
You can easily deploy several IoT services from a curated list of docker containers available from the device.

Application:

LoRaWAN gateway (multichannel, multiband)
Industrial gateway leveraging existing WisBlock modules (ModBUS, 4-20mA, 0-5V, general IO)
Edge gateway / Standalone gateway
Development platform for new products
