Boox just debuted its smallest e-reader yet. Here's what we know so far.

Boox has unveiled the Picco, its smallest e-reader yet.

The device has a 3.97-inch monochrome ePaper display, a front light, and TF card support.

Boox has not yet announced pricing or a release date.

Support for Google Play and reading apps like Kindle, Kobo, and Libby remains unconfirmed.

If supported, the tiny form factor could make it a strong pocket reader for multiple book ecosystems.
