PWB markings in RM-511 and RM-509
Mechanically RM-511 and RM-509 are almost identical except that RM-511 does not include a secondary
camera or flash. The HW differences are noticeable only by taking a closer look at the PWBs. The PWB type
code for RM-511 is 2TFA, for RM-509 it is 2TEA. The marking is located near the left soft key, behind the dome
sheet.
The PWBs of the two variants and their differences are illustrated in the following figures.
