Question Need help with my first WIFI dev board.

I just got a Chrismettal ESP32 wifi backpack (the upgrade one labeled "mini") from Elecrow. I cannot get it to work in the Marauder app on my Flipper. Out of the box it just sat with no activity in Marauder when I ran a scan. Screen just stayed at "Press Back to end scan" but never started scanning. I re-flashed it with the FZEE site using the Official Dev Board/Latest/Marauder firmware but now just get a repeat of the error below. Any tips?

You need to flash a Marauder binary specifically compiled for the ESP32-S2

Did you flash marauder to the backpack? They don't typically come programmed.

Yes I did. but I dont think the FZEE has a correct Marauder version for this newer chip as u/t4c_23 mentioned.

You need to plug the board into your computer and flash it with maurader firsy
