RAK7393 WisGate Connect Outdoor Datasheet
Overview
Description
The RAK7393 WisGate Connect Outdoor is a gateway based on the Raspberry Pi CM4/CM5, designed to support various radio modules. It features standard interfaces to accommodate different radio and backhaul configurations.
The device can function as a LoRaWAN gateway, supporting up to two (2) 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, or
- a multi-protocol gateways (e.g., LoRaWAN with mioty and LTE backhaul).
The RAK7393 supports both DC power supply (with RS485 interface for external power monitoring, such as RAK's Battery Plus solutions) and PoE. It continuously monitors its power supply, and its ultracapacitors provide backup power during outages. This ensures the system can send notifications or handle brief power interruptions seamlessly.

The RAK7393 is also compatible with the Raspberry Pi CM5. The following table shows the CPU features:
| Feature | Description |
|---|---|
| CPU | Broadcom BCM2712 |
| Architecture | ARMv8 Cortex-A76 64 bits |
| CPU core count | 4 |
| CPU nominal frequency | 2.4 GHz |
| Operating system | RAKPiOS |

| Storage | 0/16/32/64 eMMC |
PSU Input
You can choose between two main power supply solutions:
- Kway K20-T4 connector (4 pins 9-36 VDC with RS485)
- Active IEEE 802.3at PoE on 1 Gb Ethernet connector
Use only one power source (either DC or PoE) at a time. Do not use both simultaneously.
The required current from the PSU is dependent on the application and what is connected to the RAK7393. It is recommended to budget 25 W for the CM4/CM5. The PoE input voltage ranges from 42 V to 57 V, with a maximum output of 30 W on AT modules.
Interfaces
Figure 1: RAK7393 interfacesEthernet
The RAK7393 features a 1 Gb Ethernet port with PoE support, directly connected to the CM4/CM5 PHY interface.
USB 2.0 Hub
The RAK7393 board includes an onboard USB 2.0 hub, which expands a single USB 2.0 port from the CM4/CM5 into four ports:
- Three ports are available through the mPCIe connectors.
- One port is used for the RS485 (USB-UART-RS485) interface.
The RAK7393 does not leverage the USB3 interfaces available on the Raspberry Pi CM5. Only USB 2.0 signals are available on the mPCIe slots.
USB Type-C Flash Connector
The Type-C Flash connector is used to flash the eMMC on CM4/CM5 non-lite versions via rpiboot. When a Type-C cable is connected, the USB 2.0 hub is automatically disabled, and the CM4/CM5 functions as a USB device.
To enable flash mode on the CM4/CM5 module, set the flash switch to ON and press the reset button or power cycle the device.
Micro SD Card Socket
The micro SD Card socket is a PUSH-PUSH socket. To release the micro SD Card a gentle push on the micro SD card will enable it to be removed. This socket is only used with CM4/CM5 Lite modules that do not have an onboard eMMC.
Real-Time Clock
The RAK7393 has a PCF85063AT RTC onboard. A battery socket is provided for a CR2032 battery. On initial setup, the CLKOUT of the RTC should be disabled to save power. The RTC alarm output can wake the CM4/CM5 from halt mode or act as a watchdog trigger if configured.
MiniPCIe (mPCIe) Interfaces
The RAK7393 has three (3) mPCIe interfaces, which can connect different products, making the product very flexible. See the RAK7393 Compatible Hardware page for information about products supported on these interfaces.
The mPCIe interfaces schematics:

Figure 1: mPCIe slot 2 schematic
Figure 1: mPCIe slot 3 schematic- UART5 (GPIO 12/13) is available on Slot 1
- I2C1 (GPIO 2/3) is available on Slot 1
- USB2.0 is available on Slot 1, 2 and 3
- GPIO17 is reset signal on Slot 1 (SX130X_RESET)
- GPIO27 is connected to Slot 2 pin 13 with a pull-up (WAKE)
- GPIO25 is connected to Slot 1 pin 23 (RESET_GPS on some LoRaWAN concentrators)
- GPIO26 is connected to Slot 1 and Slot 2 pins 19 (PPS on some LoRaWAN concentrators)
- GPIO27 is connected to Slot 1 pin 13 with a pull-up (WAKE)
- USIM lines to external SIM slot are connected to Slot 3
UART Interface
MiniPCIe slot #1 has its UART connected to the UART5 on the CM4/CM5. If you are using, for example, a LoRaWAN concentrator with GPS support over UART, install it in this slot.
To enable the UART, add the following line to your /boot/firmware/config.txt file (under the cm4, cm5, or all section):
dtoverlay=uart5
Then, disable the login shell and enable the serial port. You can do this using raspi-config or via the command line with the following commands:
sudo raspi-config nonint do_serial_cons 1
sudo raspi-config nonint do_serial_hw 0
sudo reboot
You have to reboot the system to apply the changes. Once back the GPS data will be accesible on /dev/ttyAMA0 or /dev/ttyS0.
