An ultra-tiny, 12x13mm hardware USB injector running the Leonardo bootloader. Fully compatible with Arduino IDE and Ducky payloads. Available on Tindie.Project Details:I set out to see how small I could push an ATmega32U4 build without losing standard Arduino IDE support. The result is a 12x13mm micro-board that registers natively as a USB HID keyboard for IT automation, macro deployment, and pentesting workflows.Specs at a glance:MCU: Microchip ATmega32U4 (Native USB HID)Dimensions: 12x13mm. Bootloader: Leonardo (pre-installed) Arduino IDE + converted DScript payloads.How it works:Because the 32U4 manages the USB stack natively, no external serial converter or driver is needed. Plug it into your PC, write your payload using standard Arduino Keyboard.h calls or converted DuckyScript, and flash it straight from the Arduino IDE.Where to get one:If you want to grab an assembled board or check out the physical build:
