Bảng Mạch Phát Triển Arm Stm32 Cortex M3-stm32f103rct6 / Rbt6

(introduction to development boards)

This development board, we create for you, the design of the development board beautiful, stable use, all needles made of high-quality gold-plated materials, no longer need to worry about the long-term exposure of the phenomenon.All functions of the development board are tested on a case-by-case basis before delivery.Don't worry about quality.
This development board is a practical stm 32 development board, all io on the development board has been drawn out, very convenient for you to do secondary development.The detailed structure and functions of this development board are described in detail below.

Debug download: support jtag/swd interface debugging download, support iap.

-voltage-stabilized chips
The voltage is stabilized to 3.3 v by using ams 1117-3.3 v chip.

(interface profile)
1, jtag/swd interface
Support downloading and simulation debugging.

2. usb interface
Power supply circuit board with protective diodes with 2 high capacity electrolytic capacity (stable external power supply)

3. mcu pins interface
Introduce all pins to facilitate i/o connection with the external setting.

4,5v to 3.3v power supply input and output interface
Commonly used for external power supply or co-processing with user boards. (multi-power supply)

5,4 screws positioning holes

-a power switch (e.g. a short circuit of an external circuit can quickly turn off the power supply, and it can also be convenient for the external module to be powered from the new)

(introduction to other devices)
-power supply led
The power supply is powered by an indicator lamp.

-user led
Facilitates the i/o output test or indicates the running state of the program.

-reset button
Easy for users to reset chip programs.

4,8m crystal vibration
The main frequency can be 72 m by multiple frequency setting.

(interface profile)

1, jtag/swd interface supports downloading and debugging.

Usart1 interface
You can use usart 1 to download the program, or use usart 1 to output system information for observation.
Mcu pins interface
Introduce all pins to facilitate i/o connection with the external setting.
5v to 3.3v power supply input and output interface
Commonly used for external power supply or co-processing with user boards.
