Thanks for sharing. Now I need to find an excuse to let my school buy them ;)
@Lok24I think that might be the case. Also very useful for us trainies though!
Thanks for being part of Eurobricks and Train tech @TracerWingsong Enjoy your stay but please remember to read the rules, adhere to them and ask if something is not clear. Maybe @Barduck will be friendly enough to share some insights though.
Hmm, interest problem indeed. The Pi 5 power management is at least much better than that of the Pi 4.
You probably already saw this topic? https://forums.raspberrypi.com/viewtopic.php?t=359911
(Adjusting the USB Current Limit could be an alternative but it is as 'canonical' as the PSU_MAX_CURRENT route I guess).
It is getting a little off topic but:

Read also the seminal work of Peter Norvig and Stuart Russell. Obviously I don't think that every condition (if-then-else) statement is AI, but if we try if they are arranged systematically to simulate reasoning or decision-making processes, they could indeed be seen as part of rule-based AI.
On-topic:
Control+ seems to still be around in 2025 Technic sets!
True! But it also depends on your definition of AI, I was Russell and Norvig trained (i.e. a classical AI guy). Even if / then / else conditions could be seen as basic AI. But some basic sensor fusion and/or some tiny machine learning applications could be very useful. That is why it is so useful to have open / custom firmware.
@BrickTronic thanks that is a great list. So apparently they use the TI controllers mostly for the wireless (BLE) controller and the other controller as a main one. STM32F413 is still very able I would say so hopefully they upgrade the trains etc also to an F4, although an F0 is probably also more than sufficient.
We miss all the 12V turnouts / signals / decouplers / automated level crossings / etc from the 1980 era. For us adults we work around it but for children it a shame.
LEGO uses a TI microcontroller in Powered Up, I hope they move to e.g. STM32 which makes it easier to extend the custom firmware options :)
@M_slug357, I would think that some basic AI would be very useful, e.g. for improving sensor stuff and detecting engines etc.
