20-key left-hand keypad with encoder and screen

Overview

A set of left-hand small keyboard designed completely according to personal needs and interests. First of all, the number area and direction keys are just needed. Secondly, the more commonly used keys such as delete, shift, esc, and control can be added. During the design process, it was discovered that the direction keys occupied 4 key positions, so a five-way button was used to replace the four direction keys. This is my first time drawing a PCB
while the project documentation is being gradually completed . Please give me your advice.
