YeaCreate Nscreen32~
Features~
The Nscreen32 uses an ESP32-WROVER-IE module with a large 4-inch capacitive touch display. The display is connected via an 8-bit parallel bus resulting in a fast performance. openHASP can take advantage of the 320x480 resolution to show a large custom user-interface.
On the back there is an expansion port with 6 GPIOs (4 input only, RX & TX) so you add inputs if needed. The development board can be powered via micro USB or the 5V-in JST connector.
Pros | Cons |

8-bit parallel display | No backlight control |
16 MB flash + 8 MB PSram | Bright white power LED |

Backlight Control~
Unfortunately, there is no support for backlight control. The display is always-on.
With a small hack it is possible to control the backlight using a PNP transistor connected to GPIO0
, R8
and 3.3V
.
Documentation~
Some example projects and the schematics for the Nscreen32 can be found on the Yeacreate Github repository.
