Description

STM32F103 Minimum System Board

1 STM32 master chip introduction Powerful STM32 with STM32F103RCT6 chips, Following is the main parameters Nucleus: Cortex-M3 32-bit RISC; Frequency: 72MHz, 1.25 DMIPS / MHz; voltage: 2-3.6V; Package: LQFP64; I / O ports: 64; Storage resources: 256kB Flash, 48kB RAM (and easy to move UCGUI LWIP,.Occupy protocol packets with intensive resource ,can develop a more powerful program) Interface resources: 2xSPI, 5xUSART, 1xI2S, 2xI2C; 1xLCD, 1xSDIO, 1xUSB, 1xCAN; ADC: 3xAD (12 bit, 1us, sharing 16 channels), 2xDA (12-bit); Debugging Download: Support JTAG / SWD, support IAP.

2 the regulator chip Using AMS1117-3.3V chip ,make the voltage in 3.3v regulator voltage 3JTAG / SWD interface
Support Download and simulation debugging . 4 USB interface Power supply to the circuit board with protection diodes ,also have two high-capacity electrolytic capacitors ( power for external device stably) 5 MCU pin interface Leads to all pins, convenient to connect peripherals with I / O connections. 6 5V / 3.3V power input and output port Commonly used as the external power supply, or handle with user`s board. (Multiple sets of power) 7 4 screw positioning holes ( with copper cylinder) 8 a power switch (can quickly turn off the power such as a short circuit , as well as power supply for an external module ,more convenient) 9 the LED With Power-indicator light 10 the user LED Convenient to test I / O output or indicate situation of the program running. 11 reset button Easy for users to reset the chip program. 12 8M crystal Through the multiplier setting, make the main frequency is 72M. 13 32.768K crystal Can use for built-in RTC , or for calibration. 14 JTAG / SWD interface supports downloading and debugging. 1.USB interface can communicate with a PC. 2.USART1 interface Use USART1 to download program, or use USART1 to output system information, Then to observe. 3.MCU pin interface Leads to all pins, convenient to connect peripherals with I / O connections. 4.5V / 3.3V power supply input and output interfaces Commonly used as the external power supply, or handle with the user board PCB board size: 7.0cm * 5.0cm enter image description here
