1PCS STM32F030C8T6 microcontroller development board small system board learning board experiment board core board
Product introduction:
This is an ARM system core board based on STM32F030C8T6 as the main chip, with the power supply circuit, crystal oscillator circuit, reset circuit and program programming circuit. Reasonable circuit design ensures that the MCU can work, which can make it more convenient for users to build on this foundation. Expand your own peripheral circuits. The program can be developed using keil or IAR programming software, and the compiled program can be downloaded through SWD or ISP. The materials and technologies we provide can be used to learn ARM microcontrollers and develop products.
F0 obtains the value of nBOOT1 through the select bit in the user option byte at memory address 0X1FFFF800, instead of using two pins to set it. Together with BOOT0 pin, select boot mode to FLASH storage, SRAM or system memory
