nix module: miniature nixie tube driver modules

nix module(仮)

nix moduleはニキシー管の制御に必要な部品を2x4cmの小さな基板に詰め込んだモジュールです。高圧電源の制御や煩雑なダイナミック点灯のコードを考える必要もなく、マイコンとI2Cで接続するだけでニキシー管の制御が可能です。Arduinoライブラリと組み合わせることでシンプルにニキシー管を点灯させることができます。

最大16桁をI2C経由で連結させ、各桁を独立して制御できます。すべての数字でフェードイン・フェードアウト、シャッフルなどのエフェクトが可能です。またRGB LEDによるバックライトもついています。

Features

  • 2x4cm
  • I2Cインタフェース(プルアップ抵抗実装済み)
  • ハードウェアPWM制御
  • RGBバックライト(WS2812B互換 SK6812mini)
  • スタティック点灯でシンプルな回路構成

Open Design

回路図、BOM、PCB DesignをこのGitHub Repoで公開しています。KiCadで自由に編集可能です。

回路図(IN-12 module): Nixie_Module_IN-12_Schematics.pdf

PWMドライバはサーボモータの制御によく使われるPCA9685PW、RGB LEDはシリアル接続LEDの小型版なので、Arduino以外のマイコンボードやRaspberry Piによる制御も簡単に行えます。
