Per-key LED lighting
Solderable MX switches support
Wide variety of layouts including Tsangan bottom row, split right and left shifts, ISO enter, split backspace, F13 top row

Keyboard Maintainer: Gondolindrim
Hardware Supported: open-source PCB using the Joker template. First units were manufactured using STM32F4x1 microcontroller;
Hardware Availability: these PCBs are open-source so you can manufacture them yourself or order them from a factory. See the project's documentation for more information.

In order to flash this PCB, first build the default layout (after setting up your build environment):

make acheron/athena/<revision>:default

Where revision is the revision of your PCB. Two revisions were prototyped and sold: Alpha and Beta. Look into the label on the PCB's back to see what revision is yours. Ready-to-use binaries for the default and the VIA layouts are available in the release pages of the project's repository.

After building or downloading the firmware, put the PCB into DFU mode by holding the reset button for at least five seconds and upload the firmware onto the microcontroller through a utility like dfu-util or QMK Toolbox. Alternatively, you can build and flash using:

make acheron/athena/<revision>:default:flash
