- Update Save/Load Files menu to add for saving and loading AirTags
- Add logging to SD for Flipper/AirTag sniff
- Add Flipper Zero Sniff
- Airtag Sniffing/Spoofing
- Working Pwnagotchi Detect on all models
- Flipper BLE Spam
- Wardriving Menu added
- Added compatibility for ESP32-2432S024R 2.4" Resistive Touch USB Type-C Only
- Guide for antenna modification using ESP-WROOM-32U with built-in IPEX/U.FL
- Evil Portal examples and setup
- How to add an external antenna
- A compatible CYD module (see Compatibility)
- Chrome browser
- Data-capable USB cable
- (Optional) GPS module for enhanced functionality
- Go to the CYM Web Flasher
- Hold BOOT on your device, click "Connect" and select
- Choose the appropriate Model and Version
- Click "Program" to start flashing
- Visit the manual flasher
- Hold BOOT, click Connect
- Set memory offset and upload files
- Program
| Offset | -> | Bin |
|---|---|---|
| 0x1000 | -> | Bootloader |
| 0x8000 | -> | Partitions |
| 0x10000 | -> | Firmware |
If issues arise, try the following steps:
- Unplug and restart your CYD module
- Hold
RST, tapBOOT, releaseRST(the screen should go blank) - Refresh the Web Flasher page and click "Connect"
For further details, check out the Web Flasher repository.
Alternatively, you can flash using esptool.py by:
cd ~
git clone https://github.com/Fr4nkFletcher/Adafruit_WebSerial_ESPTool
esptool.py --port /dev/YOURSERIALPORT write_flash 0x1000 ~/Adafruit_WebSerial_ESPTool/resources/STATIC/M/CYD/esp32_marauder.ino.bootloader.bin \
0x8000 ~/Adafruit_WebSerial_ESPTool/resources/STATIC/M/CYD/esp32_marauder.ino.partitions.bin \
0x10000 ~/Adafruit_WebSerial_ESPTool/resources/CURRENT/esp32_marauder_ofyourchoice.bin
- Set up your Arduino environment following the ESP32 Marauder Arduino IDE Setup Guide
- Update your platform.txt
- Add the necessary libraries to your Arduino libraries folder
- Set the upload speed to
115200in the Arduino IDE (tested on version 1.8.19) - Upload the firmware to your CYD module
For a step-by-step guide, refer to Smoochiee's tutorial
The project has been successfully tested on:
- 2.4" Resistive Touch
- 2.8" Resistive MicroUSB-only
- 2.8" Resistive MicroUSB/Type-C 2USB
- 3.5" Resistive Touch
No hardware modifications are required, thanks to @ggaljoen's fork of the TFT_eSPI library
GPS functionality is fully supported via the 4-pin connector near the MicroUSB port. For a list of compatible GPS hardware, refer to the official wiki
| GPS | -> | CYD |
|---|---|---|
| VCC | -> | VIN |
| GND | -> | GND |
| TX | -> | TX |
| RX | -> | RX |
Note: On 2.4" and 3.5" models swap RX/TX
After flashing, you'll boot into the Marauder interface. Refer to the ESP32 Marauder Wiki for detailed usage instructions
A huge thanks to @cod5fgzj, smoochiee, ggaljoen, and ATOMNFT. And a special mention to JustCallMeKoko for their foundational work on the ESP32Marauder.
