The mobile node is effectively a shrunk down version of the standard ORBIT node designed to facilitate mobile and off-site experiments. The current generation is based around the Intel Next Unit of Computing (NUC) platform.

Hardware

NUC + CM3 (rev. 4) + B205mini-i + charger and PS

NUC

Two versions:

  1. Small: ​NUC6i5SYK with 6th generation i5-6160U processor, 32 GB RAM, 256 GB SSD
  2. Large: ​NUC6i7KYK (aka "Skull Canyon") with 6th generation i7-6770HQ processor, 32 GB RAM, 256 GB SSD
SDR Front End

The SDR front-end ​Ettus Research USRP B205mini is a full-duplex transceiver platform with tuning range of 70 MHz to 6 GHz with 56 MGHz of instantaneous bandwidth connected over USB 3.0 to the host.

USRP B205

Standard 4x4 Case Extension

The "add-on" case extension to the small version contains the B205mini-i USRP and CM3. It is a 3D printable part (STL file​) compatible with the "short" and "tall" (2.5" drive capable) versions of the 4x4 inch NUC platform. Best 3D print results have been achieved using either ABS or HIPS filament. SMA connections are provided on the outside of the case for the USRP's TX/RX, RX2, and a 10MHz or PPS time reference.

Battery Operation

A second case extension enables car deployment and graceful shutdown using the ​OpenUPS2 power supply.

Assembly instructions

These instructions assume a build based on the "short" NUC6i5SYK. Use of a taller 2.5" drive capable NUC will necessitate longer standoffs or screws.

Parts:

  • 1x 3D printed case extension
  • 8x M2.5 x 0.45mm thread, 20mm long male-female standoff
  • 4x M2.5 x 0.45mm thread, 12mm long round-head screw
  • 3x 6" right-angle SMA male to regular SMA female cable
  • 1x 6" SuperSpeed USB 3.0 A Male to Micro B Male Cable
  • connectors & cabling to connect CM3 to NUC motherboard
    • 6" "floppy power" to TE Connectivity (for standby power)
    • 6" 2x2 Molex C-grid 100mil
