Description of Arduino Resistive Interface Compatible Leonardo

Resistive touch screen TFT LCD, 4inch, 480x320 resolution. Standard Arduino interface, compatible with development boards like : Arduino UNO, Leonardo, UNO PLUS, NUCLEO, XNUCLEO. Onboard stand-alone touch controller, better touching than solutions that use AD pins directly for touch control. PWM backlight control, allows to adjust the backlight to a comfortable level; Micro SD slot, provides an easy way to store photos for displaying; Controlled via SPI, only a few Arduino pins are used

Great Single Board Computer for Creative Projects

Using this board, our team found that it was incredibly easy to interface with various sensors and modules. The compatibility with Leonardo makes it a breeze to use for people already familiar with the Arduino ecosystem. The only downside we found is that the board CAN be a bit expensive compared to other options in the market.Overall, a great choice for anyone looking to get creative with their computer projects..

Pros
  • Easy to use and compatible with resistive interfaces
Cons
  • Requires basic knowledge of programming to utilize all features

Just too slow for single board computers

Warning: Drawing on this display is very slow. The text is drawn as a 1985 1200 baud dialer. Also, in the example code, there is a 1.5 second delay just to toggle the reset pin at startup. It must not be a violation of the terms of your project. If you look at the example code, it looks like the fonts are drawn with a single pixel. simultaneously, and each pixel requires a unique SPI transaction. It's very likely that this thing could work better with the right documentation and examples. I…
