The Open Book
by Oddly Specific Objects
The Open Book is an open-hardware device for reading books in all the languages of the world. It includes a large screen and buttons for navigation, as well as audio options for accessibility and ports to extend its functionality. Its detailed silkscreen, with the all the manic energy and quixotic ambition of a Dr. Bronner’s bottle, aims to demystify the Open Book’s own design, breaking down for the curious reader both how the book works, and how they can build one for themselves.
For more detailed technical specifications, check out the Hackaday.io project page.
The Open Book is not yet available for purchase, but you can order the board from OSH Park, and the BOM is available at the project’s GitHub page. Instructions for assembly are printed on the front of the PCB.

Update UF2 Bootloader
Latest version: v3.13.0
The bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. You can check the current version of your bootloader by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FEATHERBOOT, CPLAYBOOT, etc.).
It is not necessary to update your bootloader if it is working fine. Read the release notes on GitHub to see what has been changed. In general, we recommend you not update the bootloader unless you know there is a problem with it or a support person has asked you to try updating it.
To update, first save the contents of CIRCUITPY, just in case. Then double-click the reset button to show the BOOT drive. Drag the update-bootloader .uf2 file to the BOOT drive. Wait a few tens of seconds for the bootloader to update; the BOOT drive will reappear. After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
