▸QMK Firmware — NuPhy Halo75 V2 Fork

A fork of NuPhy’s QMK firmware for the Halo75 V2, modernized against upstream QMK and extended with proper ISO layout support that NuPhy never shipped.

It started because NuPhy only publishes ANSI firmware — flashing it onto an ISO board leaves the <>, §, ' and ISO Enter keys broken. Rather than wait for a build that may never come, this fork fixes it properly and pulls the original port several major QMK versions forward in the process.

Beyond the keymap, it tackles the wireless stack (UART pin conflicts that caused ghosting, wrong STM32F072 alternate-function mode that left the nRF module deaf, USB suspend handling for RF/BT mode), the IS31FL3733 LED driver, side LED flickering, and a general cleanup of dead code and deprecated APIs. Both ISO and ANSI variants build clean, with VIA configurator support and pre-built firmware on the releases page.
