ESD Warning

Electronic components and circuits are sensitive to ElectroStatic Discharge (ESD). When handling any circuit board assemblies including Connect Tech COM Express carrier assemblies, it is recommended that ESD safety precautions be observed. ESD safe best practices include, but are not limited to:

• Leaving circuit boards in their antistatic packaging until they are ready to be installed.
• Using a grounded wrist strap when handling circuit boards, at a minimum you should touch a grounded metal object to dissipate any static charge that may be present on you.
• Only handling circuit boards in ESD safe areas, which may include ESD floor and table mats, wrist strap stations and ESD safe lab coats.
• Avoiding handling circuit boards in carpeted areas.
• Try to handle the board by the edges, avoiding contact with components.

THERMAL DETAILS

The Rudi-NX has an Operating Temperature Range of -20°C to +80°C.

However, it is important to note that the NVIDIA Jetson Xavier NX Module has its own properties separate to that of the Rudi-NX. The NVIDIA Jetson Xavier NX matches the Rudi-NX Operating Temperature Range of -20°C to +80°C.

Customer responsibility requires proper implementation of a thermal solution that maintains the RudiNX temperatures below the specified temperatures (shown in the tables below) under the maximum thermal load and system conditions for their use case.
