1.3 Module connection and mounting
Connections to the module are made by a row of 10
pads at the right hand side of the PCB. These pads are
on a 2.54mm (0.1”) pitch, which allows the use of
standard pin headers, PCB connectors and direct wiring.
Vertical mounting.
Use a 10 way 0.1” pitch right
angled pin header in the PCB
(J2). The module can then plug
into a suitable mating connector,
or be soldered directly to the
target system.
Horizontal mounting.
Use a 10 way 0.1” pitch straight
pin header in PCB (J2). Mount a
4 way header in the PCB (J1).
Do not
connect these pins to the
circuit, use them purely for
mechanical fixing.
Other options.
Use a right angled pin header to
mate with a 10 way wired
connector.
Wire the PCB directly and mount
using the four fixing holes.
