ESP32 serial port ink screen development board

Overview

Based on ESP32-SOLO-1 (less than 5 yuan a piece in a junk shop)

Onboard automatic download

Refined drive circuit (3 types of inductors and 3 types of resistors can be freely configured)

Hard SPI direct connection (faster and simpler program)

Full IO lead out (convenient for expansion)

Compatible with micropython development (micropython official website firmware does not support the single-core ESP32-SOLO-1 module, you need to compile it yourself. The compiled firmware is below)

Mainly to use micropython to debug the ink screen

Traditional Arduino development requires compilation and downloading every time. Fine-tuning the LUT for tens of seconds at a time or adjusting the registers of an unfamiliar screen driver can drive people crazy every minute.

There is no compilation process when developing with micropython. You can directly upload the source code and execute it. The efficiency is not improved at all.

As for the disadvantages of python in execution performance, it is not that important to me in the development and debugging stage.

Why do you need to build such a development board when you already have a universal driver board? I can only say that everyone who understands the harm of Dupont lines understands. . .
