Overview
Phoenix45 alpha is an open-source printed circuit board by galvy0, from the galvy0/phoenix45_alpha repository on GitHub, published under the Unlicense licence. It is a 2-layer board of 247.7 × 77.5 mm with 139 parts on 90 nets, routed with 544 tracks and 53 vias.
It is built around the ATMEGA32U4-MU and SRV05-4. Its parts include 10 capacitors, 3 switches, 2 resistors, 2 ICs and 1 connector. It belongs with the AVR (ATmega, ATtiny) boards of this library.

Layout Options
Middle Column Options
The middle column can be configured with either an OLED or a trackpoint module.
Middle Column Cover
Either case, I provide the files for a cover along with plate option to mount the cover.
Using the cover would help fill/cover up the space between the plate and the top of the case and make the middle column look more flush with the top of the case (a.k.a it's just for aesthetics).
To use the cover, you need M2 screws and standoffs - I find ~6 mm is a good length for the standoffs, though 7 mm also works well and gives enough space for the trackpoint module.
Trackpoint module
The only TP module compatible with this is the two-piece module found in ThinkPad T440/T450/T460/T470/T480, P52s, X240, X250, X260 X270 (according to https://deskthority.net/wiki/TrackPoint_Hardware).
I just bought some replacement T440/T450 keyboards from Ebay and scavanged the TP modules.
Steps (Very rough - I will try to take some photos for better instructions next time I build this):
- Unscrew the casing for the TP module.
- Install a TP cover. This can be done later.
Depending on the thickness of the cover, you may want to have hex nuts between the module and the cover so the TP sticks out as little as possible (mainly for aesthetics). - Desolder all the lines and reconnect them using flexible wires so you can readjust the position of the TP module with the TP PCB.
- Refer to the pinouts from Deskthority to connect the pins on the TP PCB to the keyboard PCB.
- With the plate standoffs pre-installed, position the TP PCB slanted through the middle column.
- Install the TP cover to the plate.
After all is done, it would look something like this:

What parts does the Phoenix45 alpha use?
139 parts, built around the ATMEGA32U4-MU and SRV05-4. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Phoenix45 alpha KiCad files?
From the galvy0/phoenix45_alpha repository on GitHub, at the commit this page was made from: the board is phoenix45_alpha.kicad_pcb and its schematic phoenix45_alpha.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Phoenix45 alpha design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
