- The adapter board that plugs in the base board and provide the input and output power connectors.
- The case, composed of the bottom and top plastic parts and the front and back metal plates.
- The hardware: screws, spacers, spings.
- A label with the device Id and the version.
When fully setup, the box should have all the software and the complete case installed.

The base firmware is common to all boxes.
To flash the base firmware to the Atmel microcontroller, follow these steps:
For flashing of the firmware, it is also required to set the GPNVM bits to 0x42.
+ In the `Device Programming` tool, select in the left sidebar `GPNVM Bits`.
+ If the value is anything other than 0x42, set the value to 0x42 and click `Program`.
+ Power ON the box using the ethernet cable.
+ Connect the Atmel adapter to the base board using the vertical port closest to the Atmel chip.
+ If using a virtual machine, enable the USB device as for the FPGA.
+ Open the Microchip software.
+ Select `Tools` #sym.arrow `Device Programming`.

+ Change the `AZURE_DEVICE_ID` field to the Id of the box from the label.
+ If needed, change the `MCU_DEVICE_ID` field to the last three characters of the Atmel chip serial.
