WebUSB STM32 Updater Tool

This tool uses the WebUSB API to perform device firmware upgrade (DFU) on STM32 devices. Paste the link to your file below and enter both the flash size, and page size for your device. This can be either in hexadecimal (e.g. 0x20) or decimal (e.g. 128). Click connect to start the DFU process. Visit our repository below to learn how this tool works, and fork your own version with whatever customizations you need. Make sure you're using Chromium or the latest Chrome Desktop.
