This is a core chip based on for CS32F103C8T6 ARM core board, features are as follows: The board based on the most basic MCU circuit, 8M and 32768 crystal circuit, USB power supply circuit. The core board is divided into two rows leads to all the I / O port. 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, USB interface, compatible with Andrews mobile phone charger interface. With double pin, the pin does not default welding, the according to their own application scenarios to their own welding direction. Keil can be used to compile, IAR compiler, can be downloaded through the or USART1 procedures, the procedures are the and debugging procedures. Chip CS32F103C8T6; Package Type: LQFP; Number of pins: 48; : -; Operating frequency: 72MHz; Storage resources: 64K Flash, 20KByte SRAM; Interface Resources: 2x SPI, 3x USART, 2x I2C, 1x CAN, 37x I / O ports, Analog-to-digital conversion: 2x (12-bit / 16-channel); Timers: 3 general timers and 1 advanced timer; Debug Download: Support JTAG / SWD debug interface to download, support for IAP. RT9193: 3.3V regulator chip, the maximum output of 300mA. Interface SWD interface: support for simulation, download and debug. Mirco-USB interface: power supply and USB communication, does not support the download. USART1 interface: USART1 can be used to download the , or use the USART1 for communication. MCU pin interface: leads all I / O port pins, easy to connect with peripherals. 5V and 3.3V power input and output interface: commonly used in external power supply, or with other modules for common ground treatment Other Device Power LED (PWR): Power indicator status, can determine whether the power supply is stable. The LED (PC13): to facilitate the I / O output test or indicate the running. jumping programming mode: (1, the flash memory SRAM 3, system memory). Reset button: reset chip for the . 8M Crystal: The frequency can be set to make the system clocked at 72MHz. 32.768KHz Crystal: Available for built-in , or for calibration. Colour: blue Material: plastic Package Contents: 1 * Development Board 2 * Pin Only the above package content, other are not included. Note: Light and different displays may cause the color of the item in the a little different from the real . The measurement allowed error is +/- 1-3cm.
