STM32F103VET6 Mini minimum system
This is a ARM core board and based on the main chip STM32F103VET6 , has the following characteristics:
1, onboard the most basic MCU-based circuits, 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 debugging download interface, the interface requires at least three lines to complete the debugging download task, compared to the traditional JTAG debugging has a lot of benefits, here insert a, JTAG now big to eliminate the trend, For example, ST's new M0 series MCU only retains the SWD debug interface, JTAG directly canceled.
4, the use of the current smart phone used by the Mirco USB interface, easy to use, do USB communication and power supply.
5, the core board of the system crystal (8MHz) use high precision high quality and low load NDK's NX5032GA, without the use of low-cost iron crystal.
6, for the STM32 RTC can not afford the problem, we have adopted the official proposal of low-load RTC crystal program, and the use of the Epson brand crystal, and did not use cheap cylindrical crystal.
7, the core board with EEPROM, model AT24C08 convenient core board for data storage.
8, power regulator chip input and output, respectively, placed a large capacity of high-capacity tantalum capacitors, will be in the regulator, filter plays an extraordinary effect, the same we have not found on Taobao than we use the capacity The greater the value of the seller, heaven and earth conscience.
9, with a high quality 2 * 24 / 2.54mm spacing of the double row of pin, to ensure good contact with electrical conductivity, user-friendly core board will be placed on the standard board or breadboard. Paier default welding, the user can choose according to their own needs welding direction.
