Open Book Touch: open-source e-reader

4 hours ago

The Open Book Touch is a compact, open-source e-book reader with a 4.26-inch front-lit e-paper touchscreen.
It supports EPUB and plain text files, features adjustable warm/cool frontlight, and uses a high-resolution display for sharp text and book covers.
The device is powered by an ESP32-S3 microcontroller, offers Wi-Fi for book transfer, and has a user-replaceable battery with up to a week of reading time.
It runs on the open-source Focus framework, is fully hackable, and includes 3D-printed enclosures that can be customized or replaced.
A comparison table highlights advantages over competitors like no DRM, open-source hardware/software, and local Wi-Fi transfer without accounts.
Manufacturing involves partnerships with NextPCB and Good Display, with shipping targeted for early 2027, though supply chain risks exist.
