1. Chip description: CS32F103C8T6; Package type: LQFP; Number of pins: 48; Core: M3; Operating frequency: 72MHz; Memory resources: 64KByte Flash, 20KByte SRAM; Interface resources: 2x SPI, 3x USART, 2x I2C, 1x CAN, 37x I/O ports, 12bit/16channel ADC; Timers: 3 general and 1 advanced; Debug/download: Supports JTAG/SWD debug interface for downloading and IAP. 2. This is a core board based on the ARM chip CS32F103C8T6. The functions are as follows: The board is built on the simplest MCU circuit, with an 8MHz and 32.768kHz crystal circuit, and a USB power supply circuit. The core board routes all I/O ports in rows. It features an SWD simulation debug/download interface for easy and fast debugging. 3. The Micro USB interface enables USB communication and power supply, compatible with standard Android mobile phone chargers. It has dualrow pins, which are not soldered by default. 4. The code can be compiled using Keil or IAR. Programs can be downloaded via SWD or USART1, and the provided programs include test and debugging routines.
