Why HYKU?
The goal of the HYKU is to create a pen tablet that is optimized for low latency. Most drawing tablets currently available offer polling rates below 200 Hz and have some level of hardware filtering that further decreases responsiveness, while the HYKU provides 600 Hz of raw sensor output.
Using the HYKU
The HYKU tablet is plug and play and requires no drivers. The screen and tablet area settings are written and saved on the tablet through the HYKU Configurator utility.
The configurator utility allows:
- Setting Screen area and Tablet area
- Setting cursor smoothing
The tablet features a single button:

Questions
How big is the Base PCB?
It measures 61 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Base use?
28 parts, built around the NC7SB3257P6X and MMBT3904. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Base KiCad files?
From the sssata/HYKU repository on GitHub, at the commit this page was made from: the board is kicad/base/base.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Base design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
