2.9-inch/1.54-inch desktop ink screen ornament

Overview

It is mainly the modification of the previous version of the hardware and the adaptation of the 1.54-inch ink screen. For details, please refer to: ESP32C3 ink screen ornaments

hardware

The ESP32C3 module is used as the main control, the ink screen is controlled through the corresponding drive circuit, and the power management is implemented through the ETA6093 chip. One switch turns on and off, and two buttons control it.

Ink screen model: 2.9 inches: HINK-E029A01 1.54 inches: HINK-E154A05

The battery lithium battery model is 301048 (3*10*48mm). Since it is not designed for low power consumption, the use and standby time are short. When using it as a desktop ornament, it is recommended to use USB power supply.

software

Use arduino for programming, and use the GxEPD2 library to implement the ink screen driver.
