Instruction
This is a multicolor graphic IPS LCD display, 2.8inch diagonal, 320×240 pixels, with resistive touch screen.
Feature
- Onboard touch controller, smoother touch experience than solutions that directly use AD pins for touching
- SPI interface, requires a few pins
- Programmable backlight control, power saving
- Comes with development resources and manual (examples for STM32/AVR/PIC)
