STM32F103C8T6 Multifunctional Development Board

Since conventional STM32 development boards require the purchase of a separate programmer, which can lead to jumper contact problems over time, and programmers are not inexpensive, this development board was designed. The main body of the board is the same as other development boards on the market, except for the addition of a programmer, greatly simplifying its use. Although the programmer uses the CH340 chip, it is completely different from those on the market. It not only features a TYPE-C interface, solving the problem of insufficient cable length in traditional programmers, making it very user-friendly for desktop users, but it also supports fully automatic downloading, compatible with both 5V and 3.3V microcontrollers, eliminating the need for manual reset; all reset functions are handled by hardware circuitry. It includes 5V and 3.3V overcurrent and short-circuit protection to prevent damage to the development board caused by reversed peripheral hardware connections or short circuits.
The pin definitions of this development board are exactly the same as the common C8T6 development board on the market; the only difference is the addition of a programmer board. This development board does not include pre-built code, but the code from Jiangxie Technology can be used. Please download the code from their official website if needed.
This section describes the software and hardware settings for fully automatic downloading
. Software settings: First, insert the development board into the computer, then click "Search Serial Ports" and select the CH340 serial port.
Hardware settings: Set boot0 to 1 and boot1 to 0. After downloading, you need to set boot0 to 0 and then press the reset button on the development board for the program to run normally.
Finally, if all settings are correct but automatic downloading occasionally fails, simply press the reset button on the downloader. (Note that the reset button on the downloader is only effective after clicking "Burning Code." Do not press the reset button on the downloader or development board when burning code normally, as this will cause the program download to fail.)
