Also they seem that changed the TI MCU (TM4C1292NCPDTI3 - G4), and what that seem to be an electric switch with a jumper. (see pics)

If you put the datasheets / pinout of the TM4C1292NCPDTI3 next to the LM3S1D21, you'll spot many similarities. I think TI renamed the former Luminary devices and hopefully fixed their issues in the process.

One major change between LM3S and TM4C is that the former is a Cortex-M3 and the latter is an M4.

nctnico:
That is just the off-the-shelve CPU core. What matters is all that is around it.

They also came back with the kapton tape on top of the big caps ...  :)

Suppose the annual failure rate is 1 in 20.  I would call that bad and that would be enough to generate howls of complaints, but if everyone had a contract, Keysight would have collected $820 for each failure.  That should cover it, I would think.  The incremental cost for an OEM to do a repair should be much less than retail.

I can promise you the AFR is much better than that :)

What does AFR stand for?
