ファームウェア

  • 公開予定

既知の不具合

  • ボトムプレートに固定用の穴が一つ足りない
  • リセット用のタクトスイッチがトッププレートと干渉するため予定していたスルーホールのスイッチではなく、高さの低い表面実装のタクトスイッチへ変更
  • トッププレートが小さく、modifier行の左右の端の1.5Uのキーが少しはみ出す

改善したい点

  • Pro Microが下側で露出するのは危険なので、ボトムプレートでカバーしたい
  • ノートPCの前に置くとケーブルが邪魔なので、横向きにだす
  • 親指で押すキーの配置を見直す

Questions

How big is the Anhedral1-mid PCB?

It measures 302.9 × 83.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Anhedral1-mid use?

117 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Anhedral1-mid KiCad files?

From the eswai/anhedral repository on GitHub, at the commit this page was made from: the board is mid/anhedral1-mid.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Anhedral1-mid design in my own project?

Its repository states no licence, so its author keeps all rights: ask eswai before reusing the design.
