Rainbow-7 - 7" 1024x600 Color Touchscreen Development Platform
Rainbow-7 is a 7” diagonal, high resolution, 1024x600 color touchscreen complete demonstration and development system for the Iridescence Graphical Framework, designed to simplify user application development. The platform is based on the combination of a 2-Mbyte FLASH STM32H753 microcontroller with 32 Mbytes of SDRAM and 32 Mbytes of external QSPI flash memory. The system can be customized by
Thornwave Labs to accommodate various customer needs both in terms of hardware and firmware.
What is included:
- 7" Touchscreen + plastic bezel
- SD card containing the user manual, pictures for the Picture Frame app and WAV files for the audio player app
- 2-pin Molex MiniFit Jr power connector + 2ft wires
