NUCLEO-F446RE w/ 16x2 LCD and Buttons

[sostupidpeople]

Good afternoon, I am doing a project on the topic of a home weather station on Nucleof44 re and it arose with the operation of the LCD Keypad shield. Maybe someone knows how to connect or work with it. I will be very grateful

The first thing to note is that Nucleo boards operate at 3V:

so you first need to check that your shield works at 3V - not 5V.

Next you will need the schematic for the shield, so you can tell how all its components are connected to the STM32.

You will also need the User Manual and schematics for the Nucleo board - available on its Product Page:

From there, it's a just a standard HD44780 LCD, and some buttons - you should be able to find plenty of examples for that.

If you're familiar with Arduino, note that there are Arduino Cores available for STM32; eg,

Schematic here? The 5V analog for the buttons might be problematic
