These PCBs are flashed with firmware and support in-switch LEDs. The GH60 supports ANSI and ISO layouts and QMK Firmware.
Please note: This is not officially a GH60, but is exactly the same in design with added features such as RGB underglow. Another name for this board is the “minila 64”.
Make sure to set LEDs to 16 in kbfirmware instead of the default 12.
