The display module seems to be a standard HD44780 16x2 display with 16-pin connector. Pre-soldered to those 16 pins is an additional board labelled "YwRobot Arduino
There are two ways to connect the LCD to your Raspberry Pi - in 4 bit mode or 8 bit mode. 4 bit mode uses 6 GPIO pins, while 8 bit mode uses 10. Since it uses up less pins, 4 bit mode is the most common method, but I'll explain how to set up and program the LCD both ways. Each character and command is sent to the LCD as a byte (8 bits) of data.
i demonstrate the device using a simple python library and show how to add such display to my ultrasonic sensor project ( https://youtu.be/jvqkzxcymum ). 0:00 intro 1:00 physical connections 2:10...
