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 |
| Capacitive Touchscreen | |
| Viewing angles | |
| External antenna |
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.
