Firmware

Flash a board, from your browser.

No Arduino IDE, no command line. A supported browser talks to the board over Web Serial and writes the firmware directly. Every ATLAS device that runs on an ESP32 flashes here. Locke, being a Raspberry Pi, updates a different way. Each panel shows the current version and what changed.

What browser flashing needs. Desktop Chrome, Edge, or Opera, a data-capable USB cable, and a page served over https or localhost. Web Serial is not available in Safari, Firefox, or on mobile. If a board will not flash, hold BOOT, tap RESET, release BOOT to force download mode, then try again.
