ikbc MK25069 keyboard software
sharkfin identifies and reads the ikbc MK25069. Free and open source. Use it in a Chromium browser with nothing to install, or download the desktop app for Windows, macOS or Linux. Either way it runs entirely on your own machine: no account, and the browser version makes no network requests once the page has loaded.
What sharkfin does with the MK25069
- sharkfin will identify this board and read its settings, but it will not write to it. Its command set is not established, and the two protocol families in this hardware share opcodes that mean different things, so a misaddressed write would land on a live register.
- You can help: the app's Contribute tab collects a read-only data bundle to paste into an issue. That is how a board moves from read-only to supported.
- Magnetic switches. This board has them. sharkfin does not configure actuation or rapid trigger: the firmware does not answer those commands. Everything else on this page still works.
sharkfin draws the MK25069 key by key, so you remap on a picture of your own board.

Connecting
Plug the MK25069 in with a USB cable. There is no configuration channel over 2.4 GHz or Bluetooth on this hardware, so a receiver or a Bluetooth pairing will not do. Settings are stored on the keyboard itself, so everything you change keeps working wirelessly once you unplug. sharkfin never flashes firmware, so there is nothing here that can brick the board. On Linux, both the browser and the app need a one-line udev rule before they can open the keyboard.
