    v3 Stable

    erin released this 2025-11-13 18:03:01 +00:00 | 1 commits to main since this release

    There's now two versions of the board, one for MBK and one for CFX. v3.mbk is fundamentally the same as v2 and uses an 18x17mm spacing between switches, which is good for FK's MBK keycaps. v3.cfx is new and uses a square 17x17mm grid for Chosfox's CFX keycaps. v3.cfx is not as wide and has different mounting hole spacing and power/reset switch positioning as a result of the narrower size.

    v3 PCBs are dated 2025-11-05; i got around to the git tagging and such a little late.

    manufacturing files

    MBK (18x17mm) and CFX (17x17mm) production files are both attached.

    gerbers/drills for PCB manufacturing: 48ish_soldered_mbk_out.zip or 48ish_soldered_cfx_out.zip
    pick and place file for PCB bottom side assembly: 48ish_soldered_mbk-bottom-pos.csv or 48ish_soldered_cfx-bottom-pos.csv
    BOM for PCB bottom side assembly: both board variants use the same file, 48ish_soldered_bom.csv

    Ordering instructions and other parts you'll need to turn these files into a completed board are otherwise the same as in v2. Pay close attention to the size of your keycaps and make sure you order the right board variant. MX spacing is not supported by either variant (yet™️). Note that with JLCPCB you'll still need to be careful that all the diodes are facing the right way.
