Understood—I’m prioritizing zero-reset switchover, using an active power-path with the regulated 5.1 V rail held continuously and enough local energy storage to ride through switching transients. The design will also detect power loss immediately while keeping the Pi running safely from the battery.
Created the Raspberry Pi 5 UPS Display HAT project requirements and power budget, targeting instantaneous active power-path switchover, a stable 5.1 V/6 A rail, and 4–6 hours from a 60–90 Wh protected external battery.
Open items
The schematic build finished in the executor, but I could not inspect or independently verify it because no ACUs remain.
ERC, component ratings, display GPIO conflicts, and zero-reset transition behavior still require review.
Next steps
Add ACUs, then request a schematic verification pass.
Confirm the exact display model and battery-pack connector/thermistor pinout.
After the schematic is clean, proceed to PCB placement and high-current routing.
Received notification from "Raspberry Pi UPS HAT" that it finished — picking the work back up.
The executor reports the UPS HAT schematic build is complete, but I cannot reconcile or independently verify its output because no ACUs are currently available.
Remaining work: inspect the schematic, run ERC, verify 5.1 V/6 A ratings and seamless switchover, check Pi/display GPIO conflicts, and validate the external battery connector pinout. Add ACUs, then request “verify and finish the UPS HAT schematic.”
