YeaCreate Nscreen32
Certification：
Nscreen32 earned Standard LVGL board certification which means the users can be sure that it’s easy to use with LVGL and they can expect decent performance and quality.
Product introduction
YeaCreate Nscreen32 is a ESP32 based display development board kit.It's included ESP32-WROVER-IE(16M Flash + 8M PSRAM), a 320x480 4 inch TFT display, a GT911 capacitance touch screen. It's also the 1st LVGL official certified board in the world.It's a cost-effective solution for embedded display.
Display
The display is built with TN technology however it has excellent viewing angle and color correctness.The DPI of the screen is also high.These bring a premium look and feel to the display.
Development
UI applications for NScreen32 can be developed with both ESP-IDF and Ardunio. As an IDE you
can use PlatformIO too.
It’s also possible to develop the UI first in a simulator on PC and copy the source files to the embedded project later.
YeaCreate provides 3 demos hosted on GitHub:

GPIO 34-39 are GPIs – input only pins.These pins don't have internal pull-ups or pull-down resistors.They can't be used as outputs, so use these pins only as inputs.External connections can be made to any GPIO except for GPIOs in the range 6-11, 16 and 17. GPIOs 6-11 are connected to the module's integrated SPI flash and PSRAM. GPIOs 16 and 17 are connected to the module's integrated PSRAM.
