RB411AH & RB411UAHL... RB411 & RB411L different...

Hi all…
As refer to the information, we have only the old file which is the RB411 series comparison but no much on this…

Appreciate if some one can share, as seem there CPU speed is same but different model of the CPU.
will be the performance is the same?

and beside the performance, what’s the different for it?

Thanks.

CPU is same clock speed, but there is no serial port on the RB411L

Dear Normis…
is’t same as well for the RB411AH & RB411UAHL?
