  • v2 59e20dc578

    v2 Stable

    erin released this 2025-09-30 03:04:09 +00:00 | 15 commits to main since this release

    fixes the weird terrible power switch trace issue from last time. also redoes the entire fucking board from scratch and its better now trust me

    manufacturing

    with JLCPCB:

    • upload gerbers from 48ish_soldered_out.zip
    • select pcb assembly
    • when prompted, upload 48ish_soldered_bom.csv as the bill of materials, and 48ish_soldered-bottom-pos.csv as the part placement file
    • verify that all the components are oriented correctly in the preview. everything will probably be rotated by 180 degrees because manufacturing standards do not exist; select everything on the bottom layer and then rotate everything so the switch pads line up and the diode orientation matches the reference on the silkscreen

    the BOM includes JLCPCB part numbers for the diodes, power switch, and reset switch which you'll pay for as part of the PCB assembly process. other components you'll need:

    • nice!nano v2
    • pins and sockets for said nice!nano v2 (low-profile is good) (https://typeractive.xyz/products/machine-sockets-and-pins)
      • typeractive
      • little keyboards
      • the sockets are through-hole but need to be trimmed flush with the front side of the board so keyswitches can go on the front. it helps to tack the sockets into place from the PCB backside first, then trim all the leads flush, then solder the frontside being careful not to use too much solder. this should leave a mostly flat surface that keyswitches can sit on top of
    • battery and battery connector
      • typeractive has this chonky 750mAh battery and jst sockets. if you want you can also skip the socket and order the battery with the extension wires that solder directly to the board; make sure you have adequate strain relief if you do
    • choc v1-compatible keycaps
    • choc v1 switches
    • you're on your own with making a case. though all the critical dimensions are documented on the board itself so it shouldn't be that bad hopefully
