RAK7391 WisGate Connect

Thank you for choosing RAK7391 WisGate Connect in your awesome IoT project! 🎉 To help you get started, we have provided you with all the necessary documentation for your product.

Product Description

The RAK7391 WisGate Connect is a Raspberry Pi CM4-based gateway designed to support various radio and WisBlock modules. It features multiple interfaces to accommodate the diverse needs of developers, including HDMI, Ethernet, USB, mPCIe, CSI, DSI, M.2, WisBlock, PoE, and Raspberry Pi HAT. Additionally, it can serve as a basic LoRaWAN gateway, supporting up to four (4) separate modules. This allows for configurations such as a 16-channel sub-GHz LoRaWAN gateway and a 2.4 GHz LoRaWAN gateway operating on the same device.

The RAK7391 provides flexible power supply options, including a DC terminal, a Phoenix terminal, and optional PoE support. It features a fan interface for CPU cooling, with control based on the CPU temperature. The device also monitors its power supply, and its ultracapacitors ensure backup power during a failure. This enables the system to send notifications or handle brief power interruptions seamlessly.
