Nova USB Modem Datasheet
Introduction
The Hologram Nova is a global-band, simple-to-use, and completely open source cellular USB modem. We've developed the Hologram Python SDK specifically for use with the Nova. Together the Nova and Python SDK are what we believe is the simplest way to get started using cellular on embedded Linux. This modem is also compatible with Linux, Mac OS, and Windows devices via an AT command interface.
At the heart of the Hologram Nova is the u-blox SARA-U201. We chose this modem family for its direct USB networking interface (available on almost any embedded linux platform), standard AT command interface, and global connectivity availability (when paired with the Hologram SIM). This USB modem is purpose-built for IoT applications and can be purchased for use in large fleets or used as a reference design for any customer application.
The Hologram Nova is designed to provide easy access to the u-blox SARA-U201 and SARA-R410-02B USB interface.
SARA series modules include a high-speed USB 2.0 compliant interface with maximum 480 Mb/s data rate. The module itself acts as a USB device and can be connected to any USB host. The USB is the suitable interface for transferring high speed data between SARA-U2 series and a host processor, available for AT commands.
The USBD+ / USBD- lines carry the USB serial data and signaling. The USB interface is automatically enabled by an external valid USB VBUS supply voltage (5.0 V typical) applied on the VUSB_DET pin.
At Hologram, we believe in providing an open platform for developers to build hardware. To support this mission, the Nova exposes the u-blox modem's UART interface as solderable pads on the top half of the board. For more advanced hardware devlopment, this provides direct access to the u-blox modem which runs at 1.8V.
Note: USE UART PADS AT YOUR OWN RISK. Pads are directly connected to the u-blox modem so using these I/O or improperly handling the board runs the risk of damaging the u-blox modem. Additionally, we do not officially provide support this interface.
Technical Specifications
Absolute Maximum Ratings (Power Inputs)
Stressing the device above one or more of the ratings listed in the Absolute Maximum Rating section may cause permanent damage. These are stress ratings only. Operating the device at these or at any conditions other than those specified in the Operating Conditions should be avoided. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.

Operating Conditions
The Hologram Nova is designed to operate within temperatures between -45°C to 85°C. It is not designed to withstand material contact with moisture or any other conductors, aside from intended use of the USB. The Hologram Nova may be installed into appropriate enclosures that can protect the device from heat, cold, moisture, and humidity for Industrial use.
If handling the Nova circuit board directly, please do so in an ESD-safe environment and wear ESD protection.

LEDs
The Nova has two clear LEDs for providing power and connectivity feedback. A power LED that represents whether the modem is on or off, and a network LED that indicates the current network status.
Note: Nova LTE-M & NB-IoT modem and Nova 3G/2G modem have same placement of LED color indicators but opposite use for power/network indication. Please use below table for reference.
