STM32F103C8T6 minimum system core board

Product introduction

This is a based on STM32F103C8T6 ARM chip core chip , has the following characteristics:

1, on board the most basic circuit based on MCU , such as crystal oscillator circuit, USB power management circuit and USB interface.

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

3, with SWD simulation debug download interface, the interface requires at least 3 lines to complete the debug download task, compared to the traditional JTAG debugging has many benefits, insert a sentence here, JTAG now have a lot to be eliminated trend, For example, ST M0 series of new MCU only retained the SWD debug interface, JTAG was canceled

4, the size is only the size of the traditional DIP40 package (such as AT89S52 ), has not yet found on Taobao smaller than the same specifications of the core board.

5, using the current Mirco USB smart phone interface, easy to use, can do USB communication and power supply.

6. For the problem that the STM32 RTC can not vibrate, we adopt the officially recommended low-load RTC crystal solution and use the Epson brand crystal instead of the cheap cylindrical crystal.

7, with a single row of high quality 1 * 40 / 2.54mm pitch pin to ensure good conductive contact, user-friendly core board placed on the standard board or breadboard. Header default is not welded, the user can choose according to their needs welding direction.

Other MCU parameters are as follows

 Interface Description: 
1, SWD interface: support for simulation, download and debugging.

2, Mirco USB interface: power supply and USB communication function, does not support download.

3, USART1 interface: USART1 can be used to download program, or use the USART1 for communication.

4, MCU pin interface: leads all I / O port pins, easy to connect with peripherals.

5, 5V and 3.3V power input and output interface: Commonly used in external power supply, or with other modules to deal with 
 
 other devices Description:

1, Power LED (PWR): power indication status, to determine whether the power is stable.

2, the user LED (PC13): easy I / O output test or indicate the program running status.

3, start jump jump to choose programming: (1, user flash 2, SRAM 3, system memory).

4, reset button: for user reset chip program.

5,8 M Crystal: frequency multiplier can be set so that the system clocked at 72MHz.

6,32.768KHz Crystal: for built-in RTC use, or for calibration.
