RAK7394 WisGate Developer CM4

Thank you for choosing RAK7394 WisGate Developer CM4 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 RAK7394 WisGate Developer CM4 is a LoRaWAN Gateway that has a cellular and a PoE variant. This gateway consists of a RAKR314 CM4 Carrier Board + Raspberry Pi Compute Module 4 (CM4), RAK2287 Concentrator, and RAK2287 Pi HAT.

The RAK7394C is the cellular variant, consisting of RAKR314 CM4 Carrier Board + Raspberry Pi CM4, RAK2287 Concentrator, RAK2013 Cellular Pi HAT for cellular connectivity, and RAK2287 Pi HAT.

The RAK7394P is the PoE variant that consists of RAKR314 CM4 Carrier Board + Raspberry Pi CM4, RAK2287 Concentrator, RAK9003 for the PoE support, and RAK2287 Pi HAT.

The RAK2287 Concentrator includes a GPS module and a heat sink for better performance and thermal heat dissipation management, and its housing is built with an aluminum casing. It also uses the SX1302 chip from Semtech® whose built-in LoRa concentrator IP core is a powerful digital signal processing engine. It can receive up to 8 LoRa packets with different spreading factors on different channels and is available in multiple variants so it can be used for international standard bands. This unique capability allows the implementation of innovative network architectures advantageous over other short-range systems.

RAK2287 Pi HAT is a converter board with a Raspberry Pi form factor that enables the RAK2287 module to be mounted on top of the RAKR314 CM4 Carrier Board. It integrates one (1) 40-pin female Pi HAT connector and one mPCIe connector to connect RAK2287 (RAK9003 in PoE variant/RAK2013 in Cellular variant) to the CM4 Carrier Board.

RAKR314 Carrier Board is designed specifically for the Raspberry Compute Module CM4 following the Raspberry Pi4 form factor. This feature-packed board includes a standard 40 PIN GPIO and supports the RAK PoE HAT, making it an excellent choice for power-over-ethernet applications.

With two USB 2.0 ports, two USB 3.0 ports, two USB-type C ports (one for power and one for programming), and an Ethernet port, this board has all the connectivity options you need. The SD card slot also provides extra storage for the eMMC CM4 modules or serves as a main (boot) for non-eMMC modules. One of the best things about the RAKR314 is that it allows you to utilize the power of the CM4 module in the familiar Raspberry Pi form factor, so you can take advantage of all your existing HATs.

RAK7389 is ideal for prototyping, proof-of-concept demonstrations, or evaluation. It includes a ready-to-use LoRaWAN Gateway OS that can be connected to a LoRaWAN server. Also, it is developer-friendly and simple even for not-so-tech users to set up a LoRaWAN system. It has to be the best value and function for connectivity to address a variety of applications like Smart Grid, Intelligent Farm, and other IoT enterprise applications.

NOTE

By default, the CM4 comes with еMMC and the SD card can be used for additional storage. The SD card can be used for Boot only with CM4 Lite models.
