Telegram channels

Public channels and groups that publish schematics, boardviews and firmware as downloadable attachments. A channel is listed only while it is reachable and actually contains files; empty and dead ones are dropped automatically.

170 channels 831,414 file posts indexed 759,521 combined subscribers

How channels are chosen

  • The channel or group is public and can be opened by its @username without an invitation.
  • It publishes real file attachments — PDF schematics, boardview files, firmware images — not just photos or adverts.
  • It still exists. Every channel is re-read once a day; if it disappears or turns private it leaves the directory.
