What customers say
Customers appreciate the significant value this kit offers, providing a complete UNO R3 board and a functional touch screen display at an accessible price point. However, the primary challenge reported is the ease of use, specifically regarding setup. New users often struggle with finding the correct libraries and documentation needed to make the 2.8 inch TFT LCD screen work immediately. While the components are generally reliable once configured, the initial learning curve for software integration is steeper than expected, requiring patience and external community support.
