# Meeting Notes

## FMUv6X

- Updated pin charts, but can’t tell on the content of the Spec.

## FMUv5X

- Double check doc and cook spec revision

📌 **TODO:** Ask manufacturers, what would you think if we published the whole schematics?  
📌 **TODO** : FMU Let’s make sure we got the data correct so we can publish to Github a new spec revision

- Make sure all links in documents resolve correctly
- Publish specs, and set a sensible roadmap for manufacturers

## FMUv2 / FMUv3

- **Option 2** : find a replacement

📌 **TODO** : Help manufacturers figure out next-steps.
