To simplify the work, it was decided to create a small card (size 43x16 mm), a mini shield that simplifies the work.
The circuit is very simple, there are some pin strips and a jumper for the backlight, there is also a 10k trimmer for contrast adjustment.
For the connection to Arduino there is an 8-pin female pin strip on which all the necessary signals including the power supply are present
