I crafted a Flipper Zero BadUSB alternative using an ESP32-S3 to automate my PC. As an Irish tech enthusiast with a Computer Science degree, I've worked in the industry since 2017 and am XDA's Lead Technical Editor. In my free time, I enjoy gaming. I built an interpreter for the ESP32-S3 that mimics Flipper Zero BadUSB scripts, enabling tasks like opening applications, automating program installation, and interacting with my PC remotely. This setup supports commands like STRING, GUI, CTRL/ALT/SHIFT, TAB, REM, and DELAY, allowing for automated interactions with my computer. I aimed for compatibility with existing Flipper Zero scripts, and the results were impressive. However, I also encountered some malicious scripts, highlighting the need for caution. The ESP32-S3's versatility is remarkable, capable of emulating various USB devices, including keyboards, mice, and MIDI controllers. It can even be used as a gamepad controller. I opted for a unique approach, creating a dedicated network for the ESP32-S3, utilizing LittleFS for script storage and a /log endpoint for debugging. This setup enables me to automate my PC in various fun and interesting ways, showcasing the ESP32-S3's potential as a powerful automation tool.
