The board should (at least) include the following features:
  • analog frontend for E1 including magnetics, like on the prototype board of tnt
  • ICE40 FPGA with USB connection
  • TVS protection on E1 and USB side
  • user button for entering DFU mode to update RISC-V firmware code
  • RGB led with light guide for status/error indication to the user

It's currently not yet entirely clear who will work on this. tnt was planning to, but laforge als indicatd that he and/or mschramm could work on it.
