About the TYPING TRAINER v5 PCB

TYPING TRAINER v5 is an open source AVR/Arduino PCB design by cuprice, published on GitHub under the MIT license. It is a 2-layer board measuring 261.1 × 81.5 mm, with 89 components from 9 distinct parts.

Its main chip is the Arduino_Nano_Every, from the AVR/Arduino family. Other key parts include the MCP23017_SP. By type, the board carries 32 switches, 32 diodes, 14 resistors, 9 modules, 1 IC and 1 buzzer.

It belongs with the keyboards designs in this gallery, and the repository also holds 1 earlier revision of it.

From the project

It's a keyboard for touch typing practice. タッチタイピング練習用のキーボード

2026.1.24 3Dプリンターを購入して、試しに特定のキーだけキーキャップをはめ込み式に変えました。あと、この先の予定としては、ダイオードや抵抗を表面実装に変更したものを作るつもりです。

I bought a 3D printer and tried changing only some keycaps to a snap-on type. Next, I plan to make a version with surface-mounted diodes and resistors.

2025.11.25 Githubに公開してから数ヶ月経ちました。それ以来、触覚を利用したタッチタイピングの練習機械が他にもあることを知り、私のウェブ検索が十分でなかったと申し訳なく思いました。他の人々の作る機械はとても複雑でレベルの高いことも知り、私はまだまだ勉強不足であると思いました。もしお嫌でなければ、学習の活動を見守っていただければ幸いです。

TYPING TRAINER v5: common questions

What microcontroller does the TYPING TRAINER v5 use?

The TYPING TRAINER v5 is built around the Arduino_Nano_Every, from the AVR/Arduino family.

How big is the TYPING TRAINER v5 PCB?

The TYPING TRAINER v5 measures 261.1 × 81.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TYPING TRAINER v5?

89 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the TYPING TRAINER v5 design files?

From the cuprice/HapticTouchTypingTrainer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the TYPING TRAINER v5 design in my own project?

Yes, under the terms of its MIT license, which cuprice chose for the repository.

Can I test firmware for the TYPING TRAINER v5 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
