XE900SL10
Layout PCB for Both XE900S-500 and XE900SL10
Despite the fact that the XE900S-500 is substantially
larger module than the XE900SL10, a common PCB
layout can be used to support both products. This
makes it easy to accommodate applications which
include nodes with both long range and short range
requirements.
The XE900S-500 and XE900SL10 can share board layout
because of common pin assignments. Pins 1 through 8
of the XE900SL10 are equivalent to Pins 3 through 10 on
the XE900S-500; they have the same functions and are
placed in the same sequence. Pin 9 on the XE900SL10 is
an unused pin and therefore does not conflict with the
ADC1 signal assigned to Pin 11 of the XE900S-500.
The XE900SL10 requires a separate pin row for Pins 10
through 14. These pins will be hidden under the XE900S-
500 module when the larger module is installed. The
XE900SL10 also includes one unique signal, Reset.
Reset is an active high signal that can be left
unconnected if no external reset is desired.
The figure below shows the overlapping layout that
supports both modules. The XE900S-500 outline and
pins are shown in green. XE900SL10 pins and outline are
shown in red.
