4Quick start
Before the first use, make sure that no damage occurred to the board during shipment:
• All socketed components must be firmly secured in their sockets
• Nothing should be loose in the board plastic bag or in the box
To start using the X-NUCLEO-GFX02Z1 expansion board, follow the steps below:
1. Plug the board onto a compatible STM32 Nucleo-144 development board
2. Download the evaluation firmware and full documentation set from www.st.com/en/product/x-cube-display
and program the target device
3. Evaluate the graphic possibilities of STM32 devices combined with the TouchGFX Engine graphic library in
X-CUBE-TOUCHGFX or develop your own application
