2.1.3 Mounting Differences
The mounting hole that existed on the GSM0107/GSM0108 is no longer present on the EDG0108. The
solder tab positions on the EDG0108 are backward compatible with the GSM0107/GSM0108.
2.1.4 Interface Pin-out Differences
The following table provides differences between the existing GSM0107/0108 modules and the new
EDG0108 platform. The pins that have changed will be detailed in sections immediately following the chart.
