Raspberry Pi UPS with auto shutdown

[st599]

Has anyone managed to find a small UPS suitable for a Raspberry Pi4 with atmospheric monitor, IMU, GPS etc attached?

Would need to signal to the RasPi to shutdown in case of a power outage.

not including ALL these things you mention, but there is this with a decent capacitor and s/w to turn off the pi gracefully:

On the plus is the serial and N2K port. Guess you can add another HAT with IMU on top. If you have N2K bus onboard, it will take the GPS coords from there
