I'm trying to make myself a little Sweep clone with Ergogen. I'm following the amazing flatfootfox guide, but the guide doesn't talk about how to make a board flippable. I also watched the Ban Vallack videos and he kinda mentioned it but it didn't really go in depth. Are there some resources on what to keep in mind when making a board flippable/repositories for flippable footprints?
The "half-swept" version of Sweep does that already: https://github.com/davidphilipbarr/Sweep/tree/main/Sweep%20half-swept
The easiest way to make the board flippable if to mount the controller upside-down on one side. Half-swept uses solder jumpers for all the pads of the controller footprint, which does basically the same thing as flipping the controller.
I found a flippable nice nano footprint and used that. here's the PCB I made. waiting for someone more experienced to tell me I didn't fuck stuff up and then I'll get it printed.
