Lately I've been playing with the Olimex esp32-poe [0]. It supports being powered over ethernet or lipo battery (or micro usb) and includes an SD card slot. If your application uses the ethernet, though, be sure to develop using a non-poe switch (or else power from the ethernet interface can leak over the usb programming interface and damage your laptop.)
