PassKey

Overview

This is a simple password recording tool based on Esp8266

This tool integrates a 0.91-inch OLED screen, connects through I2C, and comes with a CH340C serial port chip.

3 custom buttons have also been added for subsequent programming development.

Unlike the ordinary nodemcu project, this project removes the RST button and Flash button, because downloading the firmware is automatic, and these two buttons do not have much effect in actual use.

Notice

Therefore, the capacitance and resistance value is as shown on the silk screen.

Code will be released after development is completed.

The shell file is under production and will be released after verification is completed.
