for STM32F4 CAPACITIVE
Mikromedia 3 for STM32F4 CAPACITIVE 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 3 shield, connectivity can be further expanded with several mikroBUS™ sockets, additional connectors, peripherals, and so on.
Mikromedia 3 for STM32F4 CAPACITIVE is a compact development board designed as a complete solution for the rapid development of multimedia and GUI-centric applications. By featuring a 3.5" TFT display with capacitive 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.
Mikromedia 3 for STM32F4 CAPACITIVE is designed as the complete solution which can be implemented directly into any project, with no additional hardware modifications required. Four mounting holes at all four corners allow simple installation with mounting screws. For most applications, a nice stylish casing is all that is needed to turn the mikromedia 3 for STM32F4 CAPACITIVE development board into a fully functional, high-performance, feature-rich device.
At its core, there is a powerful 32-bit STM32F407VGT6 microcontroller, produced by STMicroelectronics, which provides suﬃcient processing power for the most demanding tasks, ensuring ﬂuid graphical performance and glitch-free audio reproduction.
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.
A high-quality 3.5" TFT true-color display with a capacitive touch panel is the most distinctive feature of the mikromedia 3. The display has a resolution of 320 by 240 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 3 development board. It is equipped with two different power supply inputs, offering all the flexibility that mikromedia 3 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.
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.
The MCP9700A, an integrated low-power linear active thermistor allows measurement of the ambient temperature.
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 3 can be powered ON. This can be done by a small switch at the right side of the board. By switching it ON, the PSU module will be enabled, and the power will be distributed throughout the board. A LED indicator labeled as PWR indicates that the mikromedia 3 is powered ON.
The board is equipped with the Reset button, which is located on the front side of the board. It is used to generate a LOW logic level on the microcontroller reset pin. The reset pin of the host MCU is also routed to the pin 1 of the 1x26 pin header, allowing an external signal to reset the device.
