The Andino Gateway is a 4G capable device based on the Raspberry Pi. Including a 4G/LoRa-WAN modem, RJ45 port with Gigabit Ethernet and isolated RS485 port, it can be used for both routing purposes, as well as to directly communicate with devices. Its rigid housing and connectors, modular design, DIN-Rail mountability and basis on open software standards ensure smooth, low-maintenance operation in industrial environments. The Andino Gateway contains a Raspberry Pi 3B+ or Raspberry Pi 4, depending on the configuration, which provides enough power for even resource intensive processes.
Take advantage of the standard integrated mPCI-E slot. You have the possibility to use a 4G modem / LoRa Wan network module in your Andino gateway. This increases the range of applications immensely. Thus, among other things, control tasks can be performed in
can be realized. When using a 4G modem, a SIM card is required. This is not included in the scope of delivery.
The exact connectivity of the Andino Gateway can vary depending on the configuration. This example shows the connectivity of a model using our Raspberry Pi Compute Module 4 IO Board and the AC (240V) power supply.
Depending on the ordered variant, the Gateway either comes with a 4G or LoRa-WAN modem. For both variants, an antenna can be connected via an SMA port, thus ensuring the best possible signal strength.
The modem included in the 4G version is the Simcom SIM7600E. It allows fast internet connection speeds and is connected to the Raspberry Pi via USB, which allows the usage of the maximum available bandwidth. The modem also has full support inside Raspberry Pi OS.
Included with the LoRa-WAN version comes the RAK2245 (SX1301 Chipset). It allows the gateway to be included in IOT networks and act as a receiver for LoRa-WAN sensors.
At the heart of the Gateway lies a Raspberry Pi 3B+ or 4 that can provide enough power for even more computationally heavy tasks like webservers or databases. The Raspberry Pi is connected via its 40-pin GPIO connector. This modular design allows easy replacement of parts for upgrading or in case of failure. We also continue to build custom software, including Python libraries and Node-Red nodes. Furthermore, since our software runs on Raspberry Pi OS , you can also choose from a large library of Raspberry Pi and Debian software.
The Gateway has a power supply that accepts both AC (100V-240V, 50/60Hz) and DC (24V) power inputs. This allows for more flexibility in installations and mitigates the need for a separate power supply.
The integrated, battery-buffered RTC provides the correct time even if no NTP (time) server is available. The high-precision time chip DS3231 from Dallas Semiconductors is used. Due to the internal temperature compensation of the oscillator, the chip achieves a very high accuracy of ± 2ppm at 0 ° C to + 40 ° C.
A 0.96 inch, 128 x 64 pixel OLED display, connected via I2C, enables easy monitoring of data from the Gateway. The contents of the display are fully customizable.
