STM32F030/051 development board

Used for evaluation or application development of STM32F051C8T6 microcontroller. Compatible with STM32F030C8T6.

Has the following characteristics:

• All IO interfaces are drawn out, and the onboard CH340C USB to serial port chip makes it easy to download programs or perform serial communication with a PC.
• BOOT0 chooses to use a toggle switch to avoid the trouble of plugging and unplugging jumper caps.
• Uses micro-usb, easy to find wires
• Reserved SWD interface, which can be connected to ST-LINK for debugging
• The PA4 (DAC output) interface uses an LM358 operational amplifier as a voltage follower to improve its port driving capability.
• Two touch buttons and 3 LEDs are onboard to facilitate program debugging.
• The onboard LCD1602 interface and a TFT LCD interface are compatible with most display modules you can buy online.
• Use supercapacitor as RTC backup power supply to avoid the trouble of replacing batteries
• USB interface has 500mA overcurrent protection
• Multiple power test points on board for easy testing with an oscilloscope or multimeter

Please note

• The sample code is based on the latest HAL library of STM32, uses STM32CubeMX to generate initialization code, and is developed under trueSTUDIO, and the compiler is GCC.
• My board uses a 12MHz crystal oscillator. If you use a crystal oscillator with other frequencies when soldering by yourself, please modify the RCC configuration according to your own crystal oscillator frequency (it is recommended to use STM32CubeMX for modification)
• In the RTC sample code, I use the uncommon 1601 display. If you use 1602, please make the corresponding modifications in the LCD_Config.h file yourself.
