The ESP32 module turns out to be an ESP32 WROOM-32, which is a little outdated, and I didn't see anything in the description that mentioned it was a WROOM. If you want to save pcap files to the flipper's sd card this board will not do with the currently available marauder firmwares. Still an awesome product. High gain antennas work great and breakout boards swap out nicely. Extra supports for the breakout boards can also be added fairly easily.
