Budget Flipper Zero

A flipper zero is a hardware used for authorized security testing. However, it is quite expensive. This project will build a cheaper and degraded version of the Flipper Zero.
Devlog #1
My project is to create a budget friendly version of a Flipper Zero. I have been working on this project for a few weeks now and here is what I have done so far.
- Currently working on refining the RFID/NFC cloning feature (Emulation)
- Created basic UI for the main menu and NFC feature
- Implemented MIFARE Classic authentication testing using a dictionary attack with known default keys
- Created a card identification feature that reads information such as the UID, ATQA, and SAK values to determine the card type
Components I have used so far (included in the picture):
- ESP32
- PN532
- Five buttons to control the UI
- OLED screen 128x64
Next steps:
Bridge Mode
The next major feature is a bridge mode that allows the ESP32 to act as an interface between a computer and the PN532 NFC reader. The ESP32 will be connect to the PC with USB-C. By doing so, the device will enable desktop-based NFC analysis and interoperability with NFC research tools such as mfoc. To support this function, the PN532 will be operating in UART (HSU) mode.
