+The little board to be built in this directory is going to be an addition to
+the SIMtrace family: it will be a purely passive adapter, hosting a SIM socket
+and a connector for the existing FPC cables from Sysmocom SIMtrace2 kit.  This
+passive adapter will allow strictly non-invasive observation with an
+oscilloscope, particularly observation of SIM voltages being put out by
+different old phones, without any active components that need to be powered,
+that may be damaged by 5V phones, or that may alter SIM-ME interface behaviour
+through introduction of alien power supplies, pull-ups or shifters.
