The kinX project is described in a series of blog posts:

• While not strictly a part of this series, “Hacking your own Kinesis keyboard controller” describes the first controller I built in 2013 (maybe interesting for context).

• The first post introduces the kinX, a keyboard controller with merely 0.33ms of input latency (including USB).

• The second post motivates and describes building a drop-in replacement USB hub for the Kinesis Advantage keyboard.

• The last post introduces the processing latency measurement firmware for the FRDM-K66F development board and draws a conclusion.
