The OmniScreen H7 is a display controller for a small OLED up to a 7 in RGB TFT. The MCU is an STM32H723V, with HyperBus SDRAM of 64 or 128 Mbit and SPI flash of 32 to 256 Mbit, plus EEPROM. A soldered SD NAND or a microSD card holds extra files. The sheet names TouchGFX as the graphics path, with touch input, an audio output and a PWM output for a haptic actuator.
Displays: two RGB666 ports for 4.3 in and 7 in panels, including the bias supply; SPI for 3.5 in panels and for ST7789V3; I2C OLEDs. The sheet also lists Arduino-style display modules. Links: 100 Mb Ethernet, RS-485, USB-C for data, device mode and power, with USB host as an option, and a DC input. A Li-Po charger with a state-of-charge reading and a charge counter covers a backup cell. Buck-boost regulators make the local rails. Backlight is PWM. An RGB LED output is on the board. Outline 67.1 mm by 105.4 mm. A user guide and sample code are part of the set. Ask NECOSIN for them.
