ESP32-S3 support

[RChadwick7]

Is this script compatible, or can it be made compatible with the ESP32-S3? I have an ESP32-S3-TINY board I'd like to flash.

It possibly can be made to be compatible, though I don't have one to test with. There are precompiled BINs that would be easy to add it, assuming one of them matches the board. Any more info you can provide about it such as PCB labels, VID/PID from the USB info, etc.?

The ESP32-S3 is not directly compatible with the standard Flipper WiFi devboard firmware (which targets ESP32-S2), but it can be made to work with some modifications.

Compatibility breakdown:

Board	Marauder	Evil Portal	WiFi Scanner
ESP32-S2 (official devboard)	✅	✅	✅
ESP32-WROOM	✅	✅	✅
ESP32-S3	⚠️ Partial	⚠️ Partial	⚠️ Partial

ESP32-S3 specifics:

Marauder on ESP32-S3:
The Marauder project has ESP32-S3 support in newer versions:

1. Check https://github.com/justcallmekoko/ESP32Marauder/releases for S3-specific builds
2. Flash using the web flasher or esptool:

   esptool.py --chip esp32s3 --port /dev/ttyACM0 write_flash 0x0 esp32_marauder_s3.bin

GPIO pin mapping:
The ESP32-S3-TINY may have different pin assignments than the official dev board. You'll need to verify:

• UART TX → Flipper RX (pin 13 on GPIO header)
• UART RX → Flipper TX (pin 14 on GPIO header)
• 3.3V and GND connections
• The S3-TINY form factor may not physically fit the Flipper's GPIO header

Firmware considerations:

• The S3 has dual-core Xtensa LX7 (vs S2's single-core LX7)
• USB-OTG is native on S3 (different USB stack than S2)
• WiFi capabilities are similar but the driver layer differs

Bottom line:

It's possible but requires S3-specific firmware builds and potentially different wiring. The easiest path is using a board that matches one of Marauder's supported targets. Check the Marauder docs for your exact board variant.
