Maybe a CAN bus connector, or finally a builtin user interface, if it's not just a power circuit? Built-in LCD/OLED, buttons, basic shell casing and end-user usable expansion connectors are growing trends among China/Shenzhen originating platforms like M5Stack. Arduino is still relying on hacky solutions for UI, which might be less appealing for casual users.
