Web Flasher

Flash your board over USB, straight from the browser — no esptool, no drivers.

Board Firmware version

⚠ T-Display C5 — may need the command line

This board's ROM often rejects the browser flasher's stub loader, so Install can fail with "Failed to initialize" even in download mode. If it does, flash it with esptool and --no-stub instead:

pip install --upgrade "esptool>=5"
# download mode first: hold BOOT, tap RESET, release BOOT
esptool --chip esp32c5 --no-stub write_flash 0x0 bboink-tdisplay-c5.bin

Grab bboink-tdisplay-c5.bin from the latest release. The T-Embed and Waveshare flash fine in the browser.

This browser can't flash over USB. Use Chrome or Edge on desktop (Windows / Linux / macOS). Web Serial isn't available on Firefox, Safari, or phones. You need to open this page over https.

Before you click Install

Connect the board with a USB-C data cable and pick its serial port in the popup.
Updating a board that already runs BBoink? Leave Erase device unticked — your saved config (relay URL, keys, WiFi, settings) lives in a separate partition and is preserved. Only tick Erase device for a first install on a C5 board.
After flashing a C5 board (T-Display C5 / Waveshare), unplug and replug it to start the new firmware — the C5 doesn't auto-reboot after flashing.
Board not in the port list? Use a real data cable, and if needed force download mode: hold BOOT, tap RESET, release BOOT, then Connect.
