STM32F103C8T6 ARM STM32 Minimum System Development Board

Product Introduction

This is a core chip based on STM32F103C8T6 ARM core board.

Features:

• The board is based on the most basic MCU circuit, 8Mhz crystal circuit, and USB power supply circuit.
• The core board is divided into two rows leading to all the I / O ports.
• With SWD simulation debug download interface, simple and convenient, debugging speed.
• The use of the Mirco USB interface, you can do USB communication and power supply, The USB interface, is compatible with the ordinary mobile phone charger interface.
• RTC Crystal is easy to start and more stable.
• Keil can be used to compile, and IAR compile can be downloaded through the JLink or USART1 procedures, the procedures are the owner and debugging procedures.
