51 electronic keyboard

Overview

This project is an improvement on a 51 electronic keyboard in Jiali Chuangyuan Plaza. The original project link is https://oshwhub.com/asrhdtjfkg/wei-ji-yuan-li-ke-she
The PCB and schematic are in the upper right corner. There is no problem with the PCB of this project when you open it in "Editor", but if you change the digital tube package and re-wiring, it may cause the digital tube to display errors.
The digital tube uses a common anode 8-bit digital tube.
