Lao Xuan V2 Hot-swappable + VIA version

Overview

Based on the Lao Xuan Retirement Keyboard V2 and the Lao Xuan V2 Hot-swappable version, this project has been redesigned and adapted to the new QMK firmware.

Since the Lao Xuan V2 project is three or four years old, and QMK has undergone significant updates since then, the new version of qmktoolbox no longer supports downloading .hex files, making it impossible to download firmware for the new keyboard. Furthermore, the original source code cannot be compiled, making it impossible to modify the key bindings according to personal usage habits. Therefore, this update was decided upon. Such a great open-source project should certainly continue to shine. (A screenshot of the original Lao Xuan V2 is included.)

Original project:
Lao Xuan v2 Hot-swappable version - JLCPCB EDA Open Source Hardware Platform (oshwhub.com)
Lao Xuan Retirement Keyboard V2 - JLCPCB EDA Open Source Hardware Platform (oshwhub.com)
Many thanks to Lao Xuan and the_sweet_orange for their open-source projects!

New Features:

VIA Support:

Ultra-thin casing (extremely thin, without exposing the switches)

Chamfered gasket-like positioning plate

. Attachments:
final80v2.zip (QMK folder; to compile yourself, extract to the qmk folder (qmk_firmwarekeyboards) and compile (command: qmk flash -kb final80v2 -km via)); final80v2.json (VIA (evove.top) JSON file); casing model and hardware (available on MakerWorld, verified with an A1mini; welcome to print if you have a keyboard). Also, please give a thumbs up: Lao Xuan V2 Hot-swappable Keyboard VIA Version from Seriscyberalchemist - MakerWorld
