Quick Firmware Update
One-click official firmware flashing directly from your browser over USB.
Connect your Crosspad hardware via a USB cable. When you click Update, the latest official firmware release is automatically downloaded, checked, and flashed — the STM32 co-processor first, then the ESP32 host, which restarts the device when it is done. No drivers or extra software required!
