An assistant to help you view text and picture calendars

An assistant to help you view text and picture calendars. It is mainly composed of a 2.13 inch eink(epaper) and an esp32 module.

ESP32 of espressif is used as the controller, and development environment is esp-idf v4.0.

ESP-IDF Programming Guide will teach you to install the development environment step by step.

Here you can configure the project. For example, you can change the GPIO of the screen by entering component config → Eink setting .

E-ink screen: common questions

What microcontroller does the E-ink screen use?

The E-ink screen is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the E-ink screen PCB?

The E-ink screen measures 65 × 30 mm, has 2 copper layers and is 1 mm thick.

How many components are on the E-ink screen?

55 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the E-ink screen design files?

From the TDA-2030/E-ink-screen repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the E-ink screen design in my own project?

Yes, under the terms of its Apache-2.0 license, which TDA-2030 chose for the repository.

Can I test firmware for the E-ink screen 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.
