M4-Shim

Project description

The idea is to take all the relevant pieces of the Feather M4 Express and fit them into the empty gaps of the PoE-FeatherWing.  This results in a pretty funny shaped board:

M4-Shim

The only thing that's missing compared to the Feather M4 Express is the LiPo battery charge circuitry.  Considering that this is intended to be used with Power over Ethernet, it seems like something that could be dropped to make it fit. :)
