STM32F103C8T6 minimum system core board

Product introduction

This is an ARM core board based on STM32F103C8T6 as the main chip. It has the following characteristics:

1. The most basic circuit based on the MCU, such as crystalline circuit, USB power management circuit, and USB interface.

2. The core board leads to all I/O port resources.

3. With the SWD simulation debugging download interface, the interface requires at least 3 lines to complete the debugging and download tasks. Compared with the traditional JTAG debugging, there are many benefits. Here is a statement of JTAG.For example, ST's new M0 series MCU only retains the SWD debugging interface, and JTAG is directly canceled

4. The size of only the traditional DIP40 packaging (eg, AT89S52) is only found on Taobao, which has not yet found a core board of the same specifications than us.

5. Use the Mirco USB interface used by smartphones. It is convenient to use and can be used as USB communication and power supply.

6. In response to the problem of STM32 RTC, we adopted the officially recommended low -load RTC crystal solution and used the crystal of the Epson brand without using a cheap cylindrical crystal.

7. A single row needle with a high -quality 1*40/2.54mm spacing to ensure excellent conductivity contact and convenient for users to place the core board on the standard universal board or bread board.The needle is not welded by default, and users can choose welding direction according to their needs.
