From the project

A flippable 34 key Ferris Sweep derivative with Xiao

- Utilise Seeed Xiao—it's cuter - Experiment with parts consignment for PCBA of hotswaps - Choose a battery that can be easily changed by users who do not solder (LIR1254) - Explore using CI/CD for board variants, case, and top plate generation - Locate each half's components on its respective top side for more affordable assembly and lower overall height

A flippable variant [flip] for hand-soldering, like the original half-swept. Flip is also the most cost conscious variant—about $7.60 to get 5 of the boards produced, enough for 2 full keyboads and a nice... coaster?
