ps On a separate subject I note the latest slot.it SSD decoder, the SP15d, uses a Nordic microcontroller rather than a Microchip 16F630 microcontroller and so will not be compatible with either ICP v3.3 or v4.0.1.

Is it possible that this might explain why some people are discovering that their SP15d is not working properly on an ARC Pro powered track?

I don't have one to test, but if you could check on that, and think of any reason why that might not work properly, I'm sure that user would appreciate it.

Hi MrF, so far there appears to be one report of a user having one SP15d which is giving drivability problems with the ARC PRO powerbase. Hopefully this is a one-off.

I am aware from earlier work that the ARC PRO does have stronger ‘transient’ noise spikes than the APB C7042 - particularly when very lightly loaded. A similar drivability issue was observed with ICP v3.3 and subsequently corrected as part of the ICP v4.0.1 upgrade. Not sure if this is relevant to the SP15d with standard firmware but worth mentioning.

It would be interesting if the user in question were to add a few additional digital cars onto the track (powered-up but with zero throttle) to see whether this affects the drivability issue they are seeing with their SP15d?
