I've been using this cheap ESP32-based display instead of a Flipper Zero, and it's just as versatile
For network testing, the $20 ESP32 is just as good as the Flipper Zero's Wi-Fi Devboard.
I love my Flipper Zero, and it's packed to the gills with tools for testing your hardware and software. However, its ESP32-based Wi-Fi Devboard is just an ESP32 at heart, which is why you can utilize the same tools on other ESP32-based chips, too. A custom firmware for the Flipper Zero's ESP32, Marauder, enables all kinds of attacks from Wi-Fi de-auths to packet sniffing. However, with an ESP32-powered display, you can get all of the same functionality, too. I installed it on my Cheap Yellow Display (CYD), and it can do everything the Flipper Zero's Wi-Fi Devboard can do, while being more versatile, too.
