# 2. About Your Keyboard (Version 2021-09-11)

2.1 Compatible keycaps

The keyboard comes with DSA keycaps, but is also compatible with SA and XDA keycaps. All keycaps must be 1u in size to fit this keyboard, with the exception of the thumb cluster, which can fit up to 1.5u depending on the number of keys on the thumb cluster. A 6-keyed thumb cluster will be able to fit two 1.5u keys on each side of the keyboard. A 3-keyed thumb cluster will be able to fit three 1.5u keys on each side.  The 5-keyed thumb cluster does not fit any 1.5u keys.

2.2 Non-hotswappable keyboards

Not recommended to open the back plate unless there are issues.

2.3 Compatible keyswitches for hotswappable keyboards

The hotswappable keyboard come with Kailh hotswap sockets, which are compatible with MX Cherry switches and clones including Kailh and Gateron switches. They are not compatible with low profile switches. Both three and five legged switches will work, but **five legged switches are substantially easier to insert**.
