Technical information
- Layout size: fullsize compact
- Compatible switches: MX-like only, no hotswap capabilities
- Lighting: per-key single-color through-hole LEDs. Pre-Release Beta also has RGB underglow.
- Microcontroller: STM32F072(X)(Y)(Z), where:
- x can be either 8 (64kB flash variant) or B (128kB flash variant)
- Y can be either C (LQFP48 package) or U (UFQFPN48 package)
- Z can be either 6 or 7 (higher temperature grade)
- Connector: fixed USB Type C on the bottom side, no JST connector
- Firmware compatibility: QMK (with VIA support)
- Protection hardware:
- USB data lines and power rail ESD suppressing
- USB power overvoltage protection
- Enclosure grounding pad
- Overcurrent protection
- LDO crowbar diode
- EMI suppression (shielding ferrite bead)
- Current release: pre-Release Beta (has not been prototyped yet)
- Designer: Gondolindrim
- License: Acheron Open-Source Hardware License version 1.3
Keyboard compatibility and availability
This PCB is designed to be made-to-fit the Austin keyboard and, as such, the only known compatible case is the Austin's. Also, the only known ways to obtain an Austin were through the round one and round two group buys, which are now closed and non-available.

Questions
How big is the Austin PCB?
It measures 391 × 131.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Austin use?
599 parts, built around the STM32F401RCT6, 2N7002DW, AT24C256C-SSHL-T and SPX3819M5-L-3-3. 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 Austin KiCad files?
From the AcheronProject/Austin repository on GitHub, at the commit this page was made from: the board is kicad_files/austin.kicad_pcb and its schematic kicad_files/austin.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Austin design in my own project?
Its repository states no licence, so its author keeps all rights: ask AcheronProject before reusing the design.
