Open Book Abridged Edition
About the Open Book Abridged Edition PCB
Open Book Abridged Edition is an open source ESP32 PCB design by joeycastillo, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 85 × 115 mm, with 65 components from 39 distinct parts.
Its main chip is the OSO-BOOK-C2-01, from the ESP32 family. Other key parts include the SC0918, MEM2075-00-140-01-A, GD25Q16CTIGR and R1218. By type, the board carries 19 capacitors, 12 resistors, 8 connectors, 7 switches, 5 ICs and 4 diodes.
It belongs with the iot & wireless designs in this gallery.

A note from the project creator: The Open Book was my first real electronics project; the earliest designs date to late 2019. I have learned a lot since those early days, and as such, here three years later, I am hitting reset. At this time the repository contains a version of the Open Book designed around the Raspberry Pi Pico. It's optimized for low part count and easy hand assembly, but it runs on AAA batteries and may not be as svelte as some folks might prefer. At a later date, I hope to design a followup with built-in LiPo charging and a slimmer profile, but at this time, this version…
