At under £5 each this would seem to be ideal for animations, point motor controllers and lighting rolling stock etc, or am I missing something?

Seeed or Seeed Studio does appear to be an established Arduino clone and other device producer with a decent reputation.

There seem to be a lot SAM M0+ (or similar) Arduino compatible boards available. How one decides which one to go for I don't know. Seems a good price though and the DIP-like packaging looks good for mounting on PCBs.

OK, gobbledygook over.  ;D

That looks very interesting Stephen, thanks for the info.
