Hello,
It's a case for Flipper Zero based on the implementation of a ESP32 Cam and a connector for NRF 2.4 Ghz or CC1101 (SubGhz).
I used the large prototype board from Flipper Zero, the wiring is very basic (follow for ESP32 on left pin and the plugin on the right part of FZ).
For the firmware I used Xtreme edition, but I guess if you have the Marauder Cam Apps it will work.
If you want to modify the design link
Feel free if you have any questions,
Have a great day.
