STM32F103C8T6 minimum system core board
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

This module uses an array of transistors with pullup resistors to provide an 8 channel bi-directional voltage level conversion (level shifting) for digital logic signals. Intended mainly for the conversion of signals between 3.3V and 5V logic levels this module provides a way of safely interfacing a 5V microcontroller to a 3.3V device or conversely 3.3V microcontroller to a 5V device without risking damage to both devices. Each of the 8 channels can also work in both directions meaning that bi-direction 2 way data signals can also be level shifted. Each side of the array can be supplied separately with the required level shifting voltage which can range anywhere between 1.8 and 6V.
