 - DONE get old radio driver working on NRF52
 - DONE basic test of BLE
 - DONE get a debug 'serial' console working via the ICE passthrough feature
+- add a hard fault handler
 - switch to RadioLab? test it with current radio. https://github.com/jgromes/RadioLib
 - use "variants" to get all gpio bindings
 - plug in correct variants for the real board
