This development board is our cost-effective for you to create a design aesthetic development board, development board , the use of stable , all pin are using high-quality materials made of gold-plated , no longer have to worry about with a long time to appear poor contact phenomenon occur. All functional development boards are individually tested before shipment . Do not worry about quality issues. If you find any problem within a week , you can choose to return , and we are responsible for postage , solve your worries ! The development board is a practical type of STM32 development board, development board all the IO leads are very easy to do secondary development. The following will detail the detailed structure and function of the development board .Introduction [ chip ] 1, STM32 master chip introduced STM32 powerful onboard STM32F103RCT6 chips, its core resource parameters are listed below : Nucleus : Cortex-M3 32-bit RISC; Operating frequency : 72MHz, 1.25 DMIPS / MHz; Operating voltage : 2-3.6V; Pack : LQFP64; I / O ports: 64 ; Storage resources : 256kB Flash, 48kB RAM ( so convenient transplant UCGUI LWIP more resource-intensive protocol packets can develop a more powerful program ) Interface resources : 2xSPI, 5xUSART, 1xI2S, 2xI2C; 1xLCD, 1xSDIO, 1xUSB, 1xCAN; Analog to digital conversion : 3xAD (12, 1us, sharing 16 channels ), 2xDA (12 -bit) ; Debugging Download : Support JTAG / SWD interface debugging downloads, support IAP. 2, the regulator chip Use AMS1117-3.3V chip voltage regulator is 3.3V. Introduction [ interface ] 3, JTAG / SWD interface Download and simulation debugging support . 4, USB interface Power to the circuit board with protection diodes also have two high-capacity electrolytic capacitors ( stable to give external power supply) 5, MCU pin interface Leads all pins , convenience and peripherals I / O connections. 6 ,5V and 3.3V power input and output interfaces Commonly used in the external power supply, or with the user board co manner. ( Multiple sets of power ) 7,4 screw positioning holes ( and with pillars ) 8 , a power switch ( such as a short circuit when the outside world can quickly turn off the power , but can also power external module brings new convenience ) [ Introduction] other devices 12 , the power LED Power- indicator light. 13 , the user LED Facilitate I / O output test or directs the program running. 14 , reset button Easy for users to reset chip program . 15,8M Crystal Through the multiplier setting , so clocked at 72M. 16,32.768K Crystal Built-in RTC for use , or for calibration. [Interface Overview] 17 ,JTAG / SWD interfaceSupport download and debug . USB interface USB can communicate with the PC. USART1 interface You can use USART1 download program, or use USART1 output system information , were observed. MCU pin interface Leads all pins , convenience and peripherals I / O connections. 5V and 3.3V power input and output interfaces Commonly used in the external power supply, or with the user board co manner. shipping PAYMENT TERMS: 1.we only accept payment view paypal , We apologize that we cannot accept other payment methods, such as cheque or postal orders . 2.All major credit cards are accepted through our secure payment processor PayPal 3.Payment must be received within 7 business days of auction closing.
