Description

Common Kitchen Timer With an LCD-Replacement Board

A replacement PCB board for common 4 digit 7 segment LCD kitchen timers

It uses a cheap TM1621D LCD driver. You can solder either Attiny13A, or ESP12E module.

The "Print" function can print out supported letters on the screen. However it is not optimised for memory constains for Attiny13A.

Folder descriptions:

Datasheets: Where datasheets of the components are located (also translations from Chinese)

Fabrication files: Gerber files. You can just upload those to any PCB manufacturer website to get your PCB.

Firmware: Code examples which is written using Arduino framework.

KiCAD files: KiCAD schematics and PCB files

Schematics and Layout files: PDF files for the PCB and Schematics.

If you want to use another LCD, or make your own PCB designs, I explained them in a video if you are interested. https://youtu.be/JNZbfLtlbZA
