240×135 colour IPS screen, SPI, backlight dimming
The ET-D15 is built around the 1.14" 240×135 IPS TFT, 65k colours, ST7789V controller, wide viewing angle. It talks over 4-wire SPI (write-only) + DC, RST, BL and runs from 3.3–5V; on-board LDO, level-shifted inputs.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Small colour UIs with LVGL
- Game and badge projects
- Live sensor graphs
