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.”
