+== Hardware based analysis
+
+* mPCIe modules often expose additional signals like PCM audio on
+  non-standard pins
+* existing PC/embedded mainboards don't use those signals
+* create Osmocom mPCIe-breakout board to access those signals
+* https://osmocom.org/projects/mpcie-breakout/wiki

+
+== Serial Console
+
+* EC20 solder module documents DBG_UART pinout, but not all modules
+  have it enabled?
+* serial console is at 1.8V, but the 1.8V supply is not accessible (so
+  not easy to add external level shifter / Vref)
+* create Osmocom multi-voltage USB-UART with selectable 1.8,
+  2.3, 2.5, 2.8, 3.0 and 3.3V logic level
+* https://osmocom.org/projects/mv-uart/wiki

+
+== Retro-fitting Serial Console to mPCIe module
+
+* unfortunately the DBG_URAT on the LGA module solder pads is not
+  exposed to mPCIE
+* some soldering required to retro-fit a 2.54mm header:
