From the project

Open Source Universal PCB for the a87 TKL Layout Keyboards

Geonworks에서 판매했던 Studio Kestra의 Galatea 구형 버전과 호환되는 a87 TKL 유니버셜 PCB입니다.

해당 PCB는 ISO 배열을 지원하지 않으며, 6.25u 대신 6u 하단열을 지원합니다.

또한 기존의 LED 인디케이터를 모두 버리고 Insert 키 위치에 캡스락 LED 인디케이터를 1개 배치하였습니다. 아래는 Vial의 탭댄스 기능을 활용한 인디케이터 테스트 영상입니다.

펌웨어는 QMK를 기반으로 Via와 Vial을 지원합니다. 펌웨어 소스코드와 Hex 파일은 여기에서 다운로드 받으실 수 있습니다.

What microcontroller does the Galatea Old Type 6u use?

The Galatea Old Type 6u is built around the ATMEGA32U4-MU, from the AVR/Arduino family.

How big is the Galatea Old Type 6u PCB?

The Galatea Old Type 6u measures 344.5 × 123.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Galatea Old Type 6u?

218 components, from 24 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Galatea Old Type 6u design files?

From the Clein-KR/Galatea_Old_Type_6u_PCB repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Galatea Old Type 6u design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Galatea Old Type 6u 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.
