portable Stm32 Arm Core Learning Board Module Stm32f103c8t6 Minimum SystemJJ

Descirption: brand new and high quality Features: The most basic circuit based on MCU is onboard, such as crystal oscillator circuit, USB power management circuit and USB interface. With SWD simulation debugging download interface, this interface requires at least 3 wires to complete the debugging download task. Compared with the traditional JTAG debugging, there are many advantages. I insert a sentence here. JTAG is now a trend to be eliminated, such as-ST The newly released M0 series MCU only retains the SWD debug interface, and JTAG is directly cancelled. It uses the Mirco USB interface currently used in for smart phones, which is easy to use and can be used for USB communication and power supply. In response to the problem that STM32 RTC cannot oscillate, we adopted the officially recommended low-load RTC crystal oscillator solution and used for Epson brand crystal oscillators instead of cheap cylindrical crystal oscillators. Equipped with high-quality 1x40/2.54mm pitch single-row pin headers to ensure excellent conductive contact and convenient for users to place the core board on a standard universal board or breadboard. The pin headers are not welded by default, and users can choose the welding direction according to their needs.
