The Wi-Fi dev board doesn’t come with a sd card slot installed, but there are a few addons. SD card and one that also includes GPS.

Here are the links:

Someone also found a merged MR to save to flipper’s sd card over serial, but still waiting on confirmation if it works or not. Here is the link to that: https://github.com/justcallmekoko/ESP32Marauder/pull/233

And forum post: https://forum.flipper.net/t/it-is-now-possible-to-save-marauder-pcaps-without-an-sd-card-attached-to-the-wifi-devboard/13255/12

There are a ton of add-on boards that I’m still looking at and exploring. Hopefully can bring a lot more details and information.
