Flash Annota

Web Serial · no install · runs in your browser

Flash Annota from this page.

Plug the board into this computer over USB and write the latest Annota release straight from the browser: no PlatformIO, no esptool, no drivers. The firmware is a copy of the official GitHub release served by this site, and it goes from this tab to the board over USB, nowhere else.

1 · Pick your board

ESP32-S3-ePaper-1.54 1.54" 200×200 panel, two buttons … ESP32-S3-ePaper-3.97 3.97" 800×480 panel, rotary switch …

2 · Connect & flash

Click below, then choose the board's serial port when the browser asks. You'll be offered to erase the device first: erase for a first install; skip it to update and keep your WiFi, API key and settings. The SD card is never touched.

Unsupported browser Flashing needs the Web Serial API, available in desktop Chrome, Edge and other Chromium browsers. Firefox and Safari can't do this: open this page in Chrome or Edge instead.

Secure connection required The browser only allows serial access on pages served over HTTPS (or from localhost).

Writes the bootloader, partition table and app image of the latest release (manifest). Takes 1–2 minutes; keep the board connected and this tab open.

Troubleshooting

No port in the list? The board may be in deep sleep, where its USB port disappears. Wake it, or hold BOOT while plugging the cable in to force download mode.
Board in USB drive mode? The serial port is gone while the SD card is shared as a drive. Eject the drive (or long-press Select) so the board reboots, then try again.
Still nothing? Try another cable: many are charge-only, with no data lines.
"Failed to open port"? Close PlatformIO's serial monitor, the Arduino IDE or any other program holding the port.
Board doesn't restart after flashing? Press reset, or unplug and replug it. If it's in download mode it will stay there until you do.
