I am working on a project where we will be using a dedicated RTC which will be used in an helium environment. I am just wondering if the SparkFun Real Time Clock Module - RV-8803 (Qwiic) had been tested in helium or if there is any information on any possible environment conditions that could affect operation. If not that is fine but just thought I would check. Thank you.
No prior testing…renegade!
Share your results after, though I suspect it should be fine
After you’re certain that aren’t any sustained fusion reactions, thermal management would be the next consideration. Assuming the helium environment itself is roughly STP, it’s probably no big deal for a lot of electronics that don’t get too hot.
These folks seem interested in helium.

There was this older story, too.

The most likely culprit is the SiT512, a miniaturized microelectromechanical systems (MEMS) component that Apple has used to replace bulkier quartz oscillators that are standard among mobile devices. The SiT512 has considerable advantages over quartz oscillators, but some versions of this component appear particularly vulnerable to helium intrusion. According to Apple, the best course of action to fix devices that have been exposed to helium is to turn off and unplug the device, wait a week, and turn it on again.
