ETRX2PA
3 Module Pinout
The ETRX2-PA is pin-compatible with the ETRX1, (NB: it has additional pins to the ETRX1). For
all new designs using either ETRX1 or ETRX2 it is recommended that you use the ETRX2 footprint
to ensure the option of future upgrading is guaranteed.
Figure 1: ETRX2-PA Module Pinout
The table below gives details about the 38 module pin signals for direct SMD soldering of the
ETRX2-PA to the application board. The pin numbers shown in brackets () are the related pins of
the EM250. In order to use the ETRX2-PA as a plug-in solution a Harwin 1.27mm pitch connector
can be fitted on the bottom of the ETRX2-PA (Harwin part number M50-3601042).
Other
connectors that use the same footprint may also be used, such as a Samtec TFML-110-02-S-D.
All GND pads are connected within the module, but for best RF performance all of them should be
grounded externally.
