Mikromedia 4 for STM32F4 RESISTIVE is a compact development board designed as a complete solution for the rapid development of multimedia and GUI-centric applications. By featuring a 4.3" TFT display with resistive touch screen driven by the powerful graphics controller that can display the 24-bit color palette (16.7 million colors), along with a DSP-powered embedded sound CODEC IC, represents a perfect solution for any type of multimedia application.

Once you have downloaded NECTO Studio, and since you already got the board, you are ready to start writing your first GUI projects. Start using one of the most popular graphics library in the embedded industry - LVGL graphics library, an integral part of NECTO Studio.

Resource-demanding and complex audio processing tasks can be offloaded from the host MCU by utilizing a dedicated audio CODEC IC, labeled as VS1053B. This IC supports many different audio formats, commonly found on various digital audio devices.

This development board is not limited to multimedia-based applications only. USB, digital motion sensor, battery charging functionality, SD card reader and much more expands its use beyond the multimedia.

Two standardized 1x26 pin headers expose the available MCU pins to the user, adding another layer of expandability. By using mikromedia 4 shield, connectivity can be further expanded with several mikroBUS™ sockets, additional connectors, peripherals, and so on

A high-quality 4.3" TFT true-color display with a resistive touch panel is the most distinctive feature of the mikromedia 4. The display has a resolution of 480 by 272 pixels, and it can display up to 16.7M of colors. The display module is controlled by the SSD1963 graphics driver IC from Solomon Systech. This is a powerful graphics coprocessor, equipped with 1215KB of frame buffer memory. It also includes some advanced features such as the hardware accelerated display rotation, display mirroring, hardware windowing, dynamic backlight control, programmable color and brightness control, and more.

The Power Supply Unit (PSU) provides a clean and regulated power, necessary for a proper operation of the mikromedia 4 development board. It is equipped with three different power supply inputs, offering all the flexibility that mikromedia 4 needs.

The microSD card slot allows storing large amounts of data externally, on a microSD memory card. The microSD card detection circuit is also provided on the board.

The host MCU is equipped with the USB peripheral module, allowing simple USB connectivity. Ethernet physical layer is provided by the LAN8720A, an RMII 10/100 Ethernet PHY IC from Microchip.

The RTC peripheral utilizes a separate power supply source, typically a battery. To allow continuous tracking of time, mikromedia 4 is equipped with a button cell battery that maintains RTC functionality even if the main power supply is off.

An ambient light sensor (ALS) can be used for dimming the screen intensity in low-light conditions, allowing for the lower power consumption. It can also be used to detect the proximity and turn on the screen or increase its brightness when the user approaches.

An infrared (IR) receiver with the integrated PIN diode and a demodulation section allows simple control over an IR remote controller to be implemented.

The MCP9700A, an integrated low-power linear active thermistor allows measurement of the ambient temperature.

A high-brightness RGB LED option can be used to provide visual feedback in a very simple way.

Most of the host MCU pins are routed to the two 1x26 pin headers, making them available for further connectivity. In addition to MCU pins, some additional peripheral pins are also routed to this header.

After a valid power supply source is connected mikromedia 4 can be powered ON. This can be done by a small switch at the right side of the board. A LED indicator labeled as PWR indicates that the mikromedia 4 is powered ON.
