STM32F103RBT6 Core Development Board 32F103 Small System Board STM32 Development Board
Features:
1. Onboard the most basic circuit based on MCU, such as crystal oscillator circuit, USB power management circuit and USB interface.
2. Added EEPROM (I2C/1028Byte x8) storage circuit.
3. Leads to all I/O port resources.
4. With the SWD emulation debug download interface, the interface requires at least 3 wires to complete the debug download task.
5. Using the Mirco USB interface used in current smartphones, it is easy to use and can do USB communication and power supply.
6. The core crystal system (8MHz) uses the high-quality, high-quality, low-load NDK NX5032GA without the use of a low-cost iron-shell crystal.
7. Adopted the officially recommended low-load RTC crystal scheme and used the Epson brand crystal instead of the cheap cylindrical crystal.
8. The high-capacity tantalum capacitors are placed on the input and output terminals of the power supply voltage regulator chip, which will definitely have an extraordinary effect in voltage regulation and filtering.
9. It is equipped with high-quality 2*13/2.54mm pitch double-row pin to ensure excellent conductive contact, so users can place the core board on the standard universal board or breadboard. The pin header is not soldered by default, and the user can select the welding direction according to his needs.
