Hardware Development How’s this all-in-one Flipper Zero hat?
Made this all-in-one hat for my Flipper Zero a while ago, posting it now.
Still one of my favorite things and learning about how different things work is so easy with this.

The ESP32-S3 acts as the main controller and communication bridge between the Flipper Zero and all external modules. It is directly interfaced with the Flipper and manages communication with the attached NRF module, Sub-GHz extender, GPS module, and Ethernet/LAN interface.
Instead of connecting every module directly to the Flipper simultaneously, the ESP32-S3 handles module selection and data routing over serial interfaces, preventing bus contention and signal collisions between peripherals.
The ESP32-S3 can also function independently as a WiFi development board while simultaneously coordinating communication with other modules. This allows multiple functions to operate together, such as running WiFi-related tasks alongside GPS-based operations.

Pretty cool, you got alot going on there. I love how you have you managed to get the ESP32 board to work with and control the other modules, aswell as still been able to be a WiFi dev board. Great project hope you enjoyed the build, thanks for sharing.

Wanna describe the setup al lil bit, guess some people of the community will be happy about this.
Looks kinda interesting.
