MECHANICS
6.1
Dimensions
The design of the MBa6ULxL is based on the Mini-ITX form factor (100 × 100 mm
2
). The MBa6ULxL provides for 4.3 mm mounting
holes. The Intel
®
specifications of the NUC form factor were also taken into account. The MBa6ULxL has a maximum height of
approximately 22 mm and weighs approximately 94 grams, including CR2032 battery.

Thermal management
No special precautions were taken concerning the thermal management of the MBa6ULxL. A maximum of 5 W, including
TQMa6x, have to be dissipated. More information is to be taken from the TQMa6ULxL User's Manual.
Attention:
Destruction or malfunction
The i.MX6ULx belongs to a performance category in which a cooling system is essential in most
applications. It is the sole responsibility of the user to define a suitable cooling method depending on
the specific mode of operation (e.g., dependence on clock frequency, stack height, airflow, and
software).
Particularly the tolerance chain (PCB thickness, board curvature, BGA balls, BGA package, thermal pad,
heatsink) must be ensured when connecting the heat sink. The CPU is not necessarily the highest
component. Inadequate cooling connections can lead to overheating of the TQMa6ULxL and thus
malfunction, deterioration or destruction.
