Anywhy Flake v2
A major update to axseem's open-source wireless split: Anywhy Flake v2.
Published September 22, 2025
Max aka axseem shared the Anywhy Flake v2, the latest update to this versatile wireless split coming in three sizes. Compared to the original Anywhy Flake, the PCB is now reversible and supports XIAO controllers instead of Pro Micro footprint.
I'm incredibly excited to share the latest version of my open-source project, the Flake v2! My goal was to create a comfortable, versatile, and sleek wireless split that's easy for anyone to build. After a lot of work refining the design, it's finally ready – axseem.
Features
- 40-58 keys (5x3 to 6x4). Three different sizes.
- MX and Kailh Choc (v1/v2) switch support, hotswap.
- Seeed XIAO nRF52840 controller
- Reversible PCB
- Low profile: The case is only ~9mm thick.
- Powered by ZMK firmware
Changes
Compared to v1, here are the key upgrades in v2:
- New controller: Seeed Xiao nRF52840.
- Improved PCB: Now reversible, more robust and supports both SOD-123 and SOD-323 diodes for more flexibility.
- Versatile mounting: The PCB allows for both top and bottom controller mounting (note: the current case is for bottom mount).
- Larger battery: Redesigned to fit a larger 502030 battery (~250mAh).
- Better case: The enclosure is now fully optimized for FDM 3D printing.
- Wireless only: Between-half communication is now wireless only.
According to the designer, making the decision to remove the second USB-C port was tough. The USB port that was used to connect the two halves was a bit tricky in terms of finding suppliers and soldering, while at the same time, not many people who connected their halves with a cable.
Theoretically, on a single charge, the right half can work for about 6 months when used 12 hours a day, so Max decided to go for simplicity and remove the extra USB.
The connection between the host and the keyboard still supports both wired and wireless connections, which means you can connect the left half to your computer and forget about charging for the next half year.
