LOST LICENCE KEY?

Your board already has a PRO licence, but the key is gone (e.g. after a new install with "erase")? Enter its Device ID - you see your licence here again.


How do I find the Device ID?
  1. Open the app (up-scales.com/420) and CONNECT your board - the free version is enough.
  2. Tap ⭐ FREE VERSION - UPGRADE TO PRO below the title of the app, or SCALE ✰ INFO at the bottom.
  3. The LICENCE box shows Device ID: 24EC4A1DD634 (12 characters, yours is different). Its GET PRO button opens the order form with your Device ID already filled in.
  4. No connection to the app? For developers: esptool chip-id on the board's USB port shows it as MAC (e.g. 24:ec:4a:1d:d6:34) - the same 12 characters.
