I'm thinking of building v1, easier and faster to implement. Only the B-G431B-ESC1 board is in short supply, I found the best option for about $45 on aliexpress.

V1 is the original I made about a year ago using only off-the-shelf parts. It has served me and other users well.


V4 is what we are developing now, it has gone through several revisions and several boards out in the wild. I hope to gather enough confidence to publish the board files early ...
