STM32f072c8t6 minimum system (verified)

Module introduction:
——————————————————————————————
This module uses STM32F072C8T6 as the main control chip, with STM32F103F072 minimum system, voltage regulator circuit, reset circuit, debug interface, crystal oscillator circuit, power indicator light, and a programmable LED for debugging the program. All GPIO ports of the module are brought out through pin headers, which is compact and convenient for secondary development and use.

Download aspects:
————————————————————————————
 
You can use ST-LINK to download or USB-TTL module (it is recommended to use 3.3v to download stably when connecting voltage. When downloading TTL, please connect pins PA10 (RXD) PA9 (TXD) to TXD RXD of the TTL module, set BOTT0 to 1 and BOTT1 to 0, connect the development board to TTL, open the software, check if the COM port is connected, and then burn it) Here is a brief overview of TTL download. I will put the relevant software, tutorials, drivers, lighting debugging code and BOM table in the attachment later. Please check and download it by yourself.

If it is always connected, press the RST button on the development board.

Welding:
——————————————————————————————
Most of them are 0805 chips, which are easier to weld.
The welding sequence should follow the principle of from bottom to high to avoid affecting the welding of small components. Solder the back of the circuit board first and then the front.

Because I have too many F072 series chips here, if you think the cost is high or the welding is troublesome, you are also welcome to come to my Xianyu to find me to buy the finished products, QWQ
