STM32F103C8T6 module - development board

The STM32F103C8T6 debug board is designed for prototyping devices of varying complexity. In the modern world, most devices are being developed based on STM microcontrollers, since AVR controllers cannot always cope with the task. The main advantages of the STM32F103C8T6 board compared to its counterpartArduino Nanobased on the ATmega328 microcontroller, are high performance technical parameters.

The board is designed based on the STM32F103C8T6 microcontroller with an ARM 32 Cortex-M3 core. This controller has a number of features: 72 MHz operating frequency, 64 KB Flash memory, 20 KB random access memory (RAM), 12-bit analog-to-digital converter, which provides more accurate measurement values, and 16-bit PWM.

To flash the module via USB from the Arduino IDE development environment, you need to install a specialloaderusing a ST-LINK converter. To do this, change the position of the BOOT0 jumper to "1". Change the logic of the converter to 3.3 V and connect it to the board. Detailed installation of the program in the memory of the microcontroller can be found onsite.

You can also create projects on a debug board using the STM32CubeMX development environment. The firmware is loaded onto the board through the converter. Drivers for the ST-LINK converter can be downloaded fromlink. The converter is connected to the board through 4 pins, where the VCC and GND outputs are used to supply power to the microcontroller board (3.3 V), and the TxD (data transmission line) and RxD (data reception line) outputs are connected to the A8 and A9 pins of the board . You can find detailed settings for the development environment atlink.

There are two red LEDs on the module board. When voltage is applied to the module, the PWR LED lights up, and the D0 indicator signals data transfer between the microcontroller and an external device.

The development board has 3.3V logic, so using 5V may cause technical problems. If during debugging your personal computer did not detect the module, then you need to use the RESET button.

The board is disassembled for direct connection. If necessary, you can connect the pin connectors by soldering.
