STLinkV2 compatible connector
debug print
2 x 4pin internal USB connectors
buttons: 18 independent
encoders: 4, with independent push functions
audio output stage: stereo, 2x3W

30pin header J1 is downcompatible to mcHF rf PCB so that you can use OVI40-UI in bundle with mcHF rf (version <= 0.6). Of course only features which are supported by this rf PCB will be available.
