[ STM32MP135F-DK Review] Structure and performance review
[Copy link]
Last time, I had a general intuitive understanding of STM32MP135F-DK through the functional demonstration of the factory DEMO. This time, let’s take a closer look at its structure and performance.
The STM32MP135F-DK development board is based on the Arm single cortex-A7 32-bit STM32MP135 microprocessor and is equipped with the STPMIC1 supporting power chip. Users can easily develop applications using the STM32 MPU OpenSTLinux release software, and the ST-LINK embedded debugging tool is on board.
In addition, it is equipped with rich peripheral resources for testing and development, including buttons, LEDs, a 4.3" LCD display with capacitive touch function (resolution of 480x272 pixels), a 2-megapixel CMOS camera module, Wi-Fi and low-power Bluetooth.
In addition, it provides a variety of interfaces, namely a USB Type-C connector, GPIO expansion connector, two 10/100 Mbit/s Ethernet (RMII) connectors and a microSD connector.
After completing the connection of all devices, the overall status of the development board is shown in Figure 1 and Figure 2.

There are 4 LEDs on the development board, and their pin connections and configurations are as follows:
There are 5 buttons on the board, namely 2 user buttons, 1 intervention button, 1 wake-up button and 1 reset button.
The pin connection and configuration of the button are:
In addition, the RTC is equipped with a backup power supply interface, as shown in Figure 7, and the purpose of its pins is shown in Figure 8.
