The initial speculation is that the inrush current due to the charging of the big bus capacitor in each Jaguar is causing the bench power supply to glitch causing a power on issue with the microcontroller. If this is indeed the case, it is very unlikely to affect battery operated systems.

More data will be generated when Mike has an opportunity to conduct further experiments in the team's shop. I'll respond back to the forum once I learn more.

By the way, I just updated the Jaguar microsite with the special Jaguar reorder link for FRC teams (through Digi-Key), a link to our technical support page, and a link to Luminary Micro's main webpage.

Scott,

Thanks for the update. And, thanks for the new links.

From what I have read thus far, I was not aware that the system Mike was demoing was powered by a bench supply. This information is really good to know. If in fact, powering the systems this way is not a good idea, then that information will be really good get out. Although, that info was already put out with regard to the early shipment systems. So.... maybe it now has a two fold reason. Stay tuned and we will find out.
