V1.2 board

Newer Heltec Wireless Paper. If your board's silkscreen says V1.2, pick this.

Your browser doesn't support Web Serial. Use desktop Chrome, Edge, or Opera. Open this page over HTTPS.

Before you click install

  1. Use a desktop browser: Chrome, Edge, or Opera. Safari, Firefox, and mobile browsers won't work.
  2. Plug the board into your computer with a USB-C cable that supports data (not power-only).
  3. Click the install button for your board, pick the serial port, then choose Install.

Not sure which version you have? Flashing the wrong one won't brick the board — the e-ink panel just won't draw correctly. Try the other variant if the screen looks wrong after the first boot.
