Thank you, yeah I am really looking forward to it. I hope their design includes the following:
- The castellations from the “plus” series boards
- Eliminate entirely the pad layout on the back (or at least the battery pads) and fit them into the castellation design – they can sacrifice some gpio breakouts to make it all fit. I doubt anyone will desperately need so many i/o’s.
- Provide a built-in antenna but also support adding an external ufl antenna for increased range (similar to the mg24 boards)
- An explicit raw voltage input that bypasses the power regulator – I am not entirely sure whether supplying directly to the 3.3v pin is an approved solution or a “hack”
- Explicit boot / reset buttons – this absolutely needs to be part of every Xiao going forward.
