Key Engineering Highlights
- Combines a shatterproof 10.7-inch 300 PPI flexible Carta 1300 Mobius screen with FeelWrite 2 self-healing soft film so the wear-free ceramic stylus nib indents the surface like a real gel pen on paper pad
- Right-to-repair modular internal chassis lets owners open the back cover to swap the 3,600mAh battery, expand microSD storage up to 2TB, or upgrade the main RK3566 compute module
- Executes background handwriting-to-text OCR, star-mark indexing, and Obsidian-style bi-directional note linking locally on the device without mandatory cloud subscriptions
