About the ESP32-Eink PCB

ESP32-Eink is an open source ESP32 PCB design by Outdatedcandy92, published on GitHub under the CERN-OHL-W-2.0 license. It is a 4-layer board measuring 59.2 × 29.2 mm, with 81 components from 37 distinct parts.

Its main chip is the ESP32-C3, from the ESP32 family. Other key parts include the TPS63001, USBLC6-2SC6 and BQ24074RGT. By type, the board carries 35 capacitors, 15 resistors, 8 test points, 5 diodes, 5 inductors and 4 ICs.

It belongs with the displays & leds, iot & wireless and power & battery designs in this gallery.

From the project

A tiny E-Ink display driver board featuring an ESP32-C3 and an onboard battery charging IC. It wirelessly drives a 2.13-inch E-Ink display and is designed for portable, ultra-low-power projects such as status displays, or dashboards.

ESP32-Eink: common questions

What microcontroller does the ESP32-Eink use?

The ESP32-Eink is built around the ESP32-C3, from the ESP32 family.

How big is the ESP32-Eink PCB?

The ESP32-Eink measures 59.2 × 29.2 mm, has 4 copper layers and is 1.8578 mm thick.

How many components are on the ESP32-Eink?

81 components, from 37 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the ESP32-Eink design files?

From the Outdatedcandy92/ESP32-Eink repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the ESP32-Eink design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which Outdatedcandy92 chose for the repository.

Can I test firmware for the ESP32-Eink without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
