Any updates?
"I had planned to be nearly ready to start the group buy by now and then start it around the beginning of July, but I don't believe that is a good idea. In chatting with hiney recently, and you may have seen in other conversations in the community, there are major IC shortages throughout the world. It is not impossible to acquire the chips and other components necessary for the PCBs to be manufactured, but they are much more expensive (~3x more expensive).
I will not be starting a group buy until I've come up with a solution or alternative with hiney.
More information to come following the build streams and some personal time with the board (targeting late July/early August)."
