About the Driver board
Driver board is an open source PCB design by hinatadayo, published on GitHub. It is a 2-layer board measuring 92 × 78 mm, with 35 components from 8 distinct parts.
By type, the board carries 3 connectors, 1 capacitor and 1 resistor.
It belongs with the displays & leds designs in this gallery.

nixie-token-display-schematic.md(Rev 0.2)に基づく 3 枚基板構成。 回路図・基板ともに Python (kiutils + 直接 S 式生成) でプログラム生成している。
分け方の制約はカソードバスにある。カソードは全桁で共有するので桁ごとの基板には できず、かといって管と同居させると 1 枚が大きくなりすぎる。だからカソードドライバだけ 独立させた。
カソード 10 本が全部 200V ネットで、1 本あたり 1.3mm の通り道が要る (線幅 0.3mm + クリアランス 1mm)。この 10 本は全部の管に行くので、 管 1 本の脇を必ず 10 本とも通過する。管どうしの隙間は ピッチ − 15.1mm:
4 桁が、管基板を 100×100 に収められる最大の桁数。 仕様書 1 章の 3 モード (残量 %、トークン数、リセットまでの時間)はいずれも 4 桁で表現できる。 6 桁にするなら 4 層化するか沿面 1mm を緩めることになり、どちらも設計判断。

Driver board: common questions
How big is the Driver board?
The Driver board measures 92 × 78 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Driver board?
35 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the Driver board design files?
From the hinatadayo/nixie-token-display repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Driver board design in my own project?
The repository has no license, so all rights stay with hinatadayo. Use it as a reference, and ask the author before reusing the design.
