This is one of the last developments related to rubber ducky or bad USB devices. This device is based on the ATMEGA32U4 microprocessor which can emulate many USB modes like HID, used for injecting key presses to the target system.
The main processor is based on the Arduino Leonardo R3 development board and the improvement is that a microSD card slot is included to allow storing many different payloads. The microSD card has to be FAT32 formatted to be recognized.
You can find the firmware and the instructions for flashing it in the following github:
