AJAZZ keyboard software
sharkfin is a free, open-source replacement for the AJAZZ app: remap keys, set the RGB, paint per-key colour and record macros. Use it in a Chromium browser with nothing to install, or as an app on Windows, macOS and Linux. It runs entirely on your own machine, with no account.
Does sharkfin support my AJAZZ board?
The table lists every AJAZZ model sharkfin knows, 1 in all. If yours is missing, plug it in anyway: these boards report their own device id, and sharkfin identifies anything built on ROYUAN hardware from that reply.
| Board | Writable | Layout |
|---|---|---|
| AK820 MAX | yes | slot grid |
"Writable" means sharkfin will change settings on it. Read-only boards are ones whose command set is not established yet; sharkfin identifies them and reads from them, but refuses to write, because the two protocol families in this hardware share opcodes that mean different things.
