ESPHome Device Builder adds browser-based USB installation for Raspberry Pi Pico boards and for nRF52 devices that use the Adafruit bootloader. Makers can compile a configuration and install its firmware from the dashboard. The nRF52 installer also joins the standalone ESPHome Web tool.
The Pico installer supports RP2040 boards, including a tested Pico W, and refuses RP2350 images. A Pico already running ESPHome can restart into its installation mode automatically; a first installation needs that mode selected by hand. Browsers without WebUSB download the firmware with instructions to copy it to the Pico instead. Pico owners also gain USB logs in the browser.
Contributor tomaszduda23 makes a first contribution to the Device Builder frontend with the nRF52 installer, drawing on jonasniesner’s tools. J. Nick Koston adds the Pico installer and logs. A companion nRF52 correction gives the bootloader enough time to erase memory without the device restarting during installation.
