    Details: open103r standard stm32f103r mcu arm cortex-m3 stm32 ad da developmen?t board
    descriptions:
    - open103r is a stm32 development board that features a stm32f103rct6 device as the microcontroller. there are further expansions with various optional accessory boards for specific application. the modular and open design makes it the ideal for starting application development with stm32f family.

    1.stm32f103rct6: the high performance stm32 mcu in lqfp64 package which features
    core: arm cortex-m3 32-bit risc;
    operating frequency: 72mhz, 1.25 dmips/mhz;
    i/os: 51;
    operating voltage: 2-3.6v;
    memories: 256kb flash, 48kb ram;
    communication interfaces: 2 x spi, 5 x usart, 2 x i2s, 2 x i2c, 1 x sdio, 1 x usb, 1 x can;
    ad & da converters: 3 x ad(12-bit, 1μs, shares 16 channels); 2 x da(12-bit);
    debugging/programming: supports jtag/swd (serial wire debug) interfaces, supports iap;
    2.ams1117-3.3v: 3.3v voltage regulator;
    3. power supply switch: 5v dc or usb;

    22.5v dc jack;
    23.5v/3.3 v power input/output, usually used for power output, or common ground with other user board;
    24.mcu pins connector: all the mcu pins are accessible on expansion connectors for further expansion;
    25.jtag/swd interface: for debugging/programming;
    26.boot mode selection: for configuring the boot0 and boot1 pins;
    27.usb enable jumper
    short the jumper to enable the pc auto detection while usb connecting;
    open the jumper to disable;
    28.ps/2 interface jumper
    short the jumper to connect the ps/2 device to i/os that used in example code;
    open the jumper to connect the ps/2 device to other custom pins via jumper wires;
    29.leds jumper
    short the jumper to connect the leds to i/os that used in example code;
    open the jumper to connect the leds to other custom pins via jumper wires;
    30.user key jumper
    short the jumper to connect the user key to i/os that used in example code;
    open the jumper to connect the user key to other custom pins via jumper wires;
    31.joystick jumper
    short the jumper to connect the joystick to i/os that used in example code;
    open the jumper to connect the joystick to other custom pins via jumper wires;
    32.vbat selection jumper
    short the jumper to use system power supply;
