Connecting the GSM module to DSB45

To properly connect the GSM module to the DSB45 platform use the appropriate backpack
adapter provided with DSB45. For detailed information refer to [3]. The backpack adapter
connects to the DSB45 PCB via the 50-pin plug connector X150.
Note: The pin assignment of the 50-pin board-to-board connector X150 might be different
to the pin numbering of the GSM module.
