Hologram Nova Software-Defined Cellular Device

The Hologram Nova is a software-defined cellular device that leverages a global telecommunications network to provide connectivity to devices in over 200 countries. Its core component is an industrial-grade u-blox SARA, which enables the development of a variety of IoT applications. The Nova ships with FCC, PTCRB, CE, and AT&T certifications. It is compatible with a wide variety of single-board computers, including Arduino, Raspberry Pi, and other programmable boards.

Hologram Dash

The Hologram Dash Nova is a smart IoT device that relies on cellular connectivity to operate. Its platform is based on cellular IoT and works with 470 carriers worldwide. The device uses a SIM card that can connect devices through 2G to 4G LTE networks and newer CAT-M and eSIM technologies. Its coverage area reaches 200 countries and relies on 470 carriers. Hologram’s SIM cards support eUICC technology and are remotely updateable. Available in either a triple-cut card or MFF2 embedded form factor, the SIM card can work with a variety of IoT devices.

Hologram also offers an open source version of the Dash. With the open-source version of the Dash, anyone can develop and maintain their own IoT devices. Users can install applications on their devices to access the data and keep track of fleet health. Hologram also offers alerts regarding usage, data limits, and device health. Depending on the configuration, Hologram can offer email notifications and move SIMs from one device to another.

Developers can begin developing their application on the Hologram Platform with a Raspberry Pi or a Hologram Cloud. Those interested in building a custom IoT device can begin by integrating the Hologram SDK and the Hologram Cloud. Once they are comfortable with the platform, they can easily move from a standard Raspberry Pi 3 to a custom PCB that integrates the same ublox module as the Hologram Nova.

The Nova platform is open source and is fully scalable. Nova supports 2G/3G/LTE Cat-M connectivity across 200 countries. It is tightly coupled with Hologram’s Software Development Kit (SDK) for IoT connectivity. It has an IP67 certification and FCC and PTCRB compliance. The Nova ships with a wide range of other certifications, including AT&T. It can be used for industrial and IoT projects and more.

Ubidots support the Hologram Nova with Raspberry Pi. They can also be used to deploy cellular connected monitoring solutions. The Hologram Dash Nova can be connected to Ubidots dashboards to keep track of temperatures and other information. The Hologram Python SDK also supports communication with the Ubidots platform. This platform provides API and webhook support. The Hologram Python SDK is designed to be able to communicate with both platforms.

The Hologram Dash Nova features a SIM card that comes with the device for free. To activate the SIM, the Raspberry Pi starts the Nova modem. The LEDs on the device provide feedback to the user. The Blue LED indicates the modem is turned on and the red LED informs the user of the current network status. The SIM card is used to communicate with Hologram’s cloud server through a Cloud Services Router. The Cloud Services Router forwards the messages to Ubidots, a company that provides analytics for IoT solutions.

Another feature of the Hologram is that it allows users to SSH into the devices they’ve connected to it. This feature isn’t useful for small deployments, but it is very important for large-scale sensor networks. Unlike some other devices, Hologram’s platform allows users to route messages through the system. Its CLI and Python SDK guides are comprehensive. These guides provide more information about the Hologram Dash Nova and how to use it.

The recording medium for a hologram is silver halide, which has higher concentration of light-reactive grains than other types of photography film. These grains are attached to a transparent substrate, usually glass. A random pattern is created when the points of light interact with each other. It is possible to view a hologram on a computer monitor using a microscope, but you cannot identify the subject by looking at the pattern.

The hologram can be cut in two, showing the entire scene in each half. Each piece of the hologram records information on all points of light in the scene. It is like looking at a street from two different windows. This way, it is possible to see the street from various perspectives. The hologram displays three-dimensional images and is perfect for use in holographic presentations. You can even take a picture of a street and see it through both windows.
