This WiFi Devboard is based on ESP32-S2 and is made specially for Flipper Zero
Allows advanced in-circuit debugging via USB or Wi-Fi using the Black Magic Probe open source project
As a bonus, ESP32-S2 allows Wi-Fi penetration testing (PMKID capturing, deauth, and more) and connects Flipper Zero to the Internet. These functions are not supplied with the module and must be implemented additionally.
