I have a Jetson Orin Nano that had two capacitors broken off (or at least I believe they’re capacitors). The module does not boot anymore. I have had a difficult time figuring out exactly what capacitors these are. I tried to measure them with a multimeter and get readings of around 16-18uf, and they appear to be 0805 packages. I would like to replace them with an equivalent if I could get the specs for these.
Unfortunately, one of the capacitors ripped a pad off, so I was wondering if these two caps were in parallel and I would be able to replace them with a single larger cap - or stack two on top of each other. I understand that this isn’t ideal, but I would like to get this module working again if possible.

I’d be happy to help you troubleshoot the issue with your Jetson Orin Nano module!
Firstly, I’d like to acknowledge that it’s great that you’ve taken the initiative to investigate the issue and try to measure the capacitors. However, I must emphasize that replacing capacitors on a PCB can be a delicate process, and it’s essential to exercise caution to avoid causing further damage.
Based on your description, it appears that the two capacitors in question are likely part of the power filtering or decoupling circuitry on the module. The 0805 package size and 1618uF capacitance value suggest that they might be X5R or X7R ceramic capacitors, which are commonly used for power filtering and decoupling applications.
Before we proceed, I’d like to clarify a few points:
Capacitor values: While you’ve measured the capacitance value to be around 1618uF, it’s essential to note that this value might not be entirely accurate, as the measurement could be affected by the capacitor’s tolerance, temperature, and other factors.
Capacitor type: Without more information about the capacitor’s type, voltage rating, and temperature coefficient, it’s challenging to recommend a suitable replacement.
Parallel configuration: If the two capacitors were indeed in parallel, replacing them with a single larger capacitor might be possible. However, this would depend on the specific circuit design and the required capacitance value.
To better assist you, I’d like to request more information:
PCB layout: Could you provide a clear photo of the PCB layout around the broken capacitors? This might help us identify the capacitor values, types, and configurations.
Schematic diagram: If you have access to the module’s schematic diagram, please share it with me. This would provide valuable information about the circuit design and the capacitors’ roles.
Module documentation: Have you checked the Jetson Orin Nano module’s documentation, such as the datasheet or user manual, for information about the capacitors and their replacement?
Once I have more information, I can provide a more informed answer and guidance on how to proceed with replacing the capacitors.
In the meantime, I’d like to caution you against attempting to replace the capacitors without proper knowledge and equipment. If you’re not experienced in PCB repair and capacitor replacement, it’s recommended to seek professional help to avoid causing further damage to the module.
Please feel free to provide more information, and I’ll do my best to assist you in getting your Jetson Orin Nano module working again.

I was unable to find any relevant documentation on the Orin Nano compute module - schematics or layout. I do not think that this is publicly available; I believe only a person could help with this matter. I would be happy to attempt the repair myself if I can confirm the capacitance and parallel config of the caps.
