Connectivity & expandibility

mikromedia HMI 7 offers USB-UART connectivity via the USB Type-C connector. Besides that, it also offers two standardized mikroBUS™ Shuttle connectors. This represents a considerable upgrade for the system, as it allows interfacing with the huge base of Click boards™.

The microSD card slot enables large amounts of data to be stored externally, on a microSD memory card. A microSD card detection circuit is also provided on the board.

The host MCU can be programmed and debugged over the JTAG/SWD compatible 2x5-pin header. This header allows an external programmer (e.g. CODEGRIP or mikroProg) to be used.

Display & Graphics controller

A high-quality 7” TFT true-color display with a capacitive touch panel is the most distinctive feature of the mikromedia 7. The display has a resolution of 800 by 480 pixels, and it can display a true-color palette of 16.7M of colors (24-bit color depth).

The display module is controlled by the FT813 graphics driver IC from FTDI. This is a powerful graphics controller targeted at embedded applications and able to generate high-quality Human Machine Interfaces (HMIs). It also includes advanced features such as the embedded video engine, enhanced sketch processing, built-in synthesizer, and more.

Peripherals

To round-up its multimedia concept, mikromedia HMI 7 features an audio speaker paired with a Class-AB audio amplifier, an ideal combination for various sound-related applications.

The haptic feedback motor peripheral features a compact size Eccentric Rotating Mass (ERM) motor. This motor contains a small eccentric weight on its rotor, so while rotating it also produces a vibration effect. This is an ideal solution for adding a simple, one pin driven haptic feedback on any design.
