سازنده: RNGO

برد آموزشی صنعتی ARM با استفاده از میکروکنترلر STM32F103 که متعلق به شرکت STMicroelectronics می باشد طراحی شده است. امکانات فراوان این برد باعث می شود تا به راحتی و بدون نیاز به ابزار جانبی دیگری پروژه های مختلف و گوناگونی را انجام دهید.
امکانات سخت افزاری برد:
1- Processor MCU
STM32 Shenzhou III development board processor is STM32F103ZET6, the processor is based on ARM C7 Cortex-M3 core architecture, clocked at 72Mhz, the internal 512K bytes of FLASH and 64K bytes of SRAM, LQFP144 package.
2- USB 2.0 full speed interface (both power and USB capabilities(
STM32 Shenzhou III development board contains a USB 2.0 full-speed interface, you can use the USB port on the development board for power supply and as a USB SLAVE slave interface.
3- DC 5V power connector
STM32 Shenzhou III development board provides 5V DC power input interface, DC power adapter in line with common power adapter interface standard, DC power supply seat inside the positive power supply, the negative power supply outside. Development Board has both USB and DC power supply interface.
4-Power chip
STM32 Shenzhou III development board using the 3.3V power supply to the CPU, because the CPU voltage is 3.3V, so we need to convert the external 5V voltage to 3.3V. In addition many, many ICs should work under 3.3V supply conditions.
5- Power selection switch
Through the power selector switch can control the USB power supply, or DC 5V power outlet, or power off the board; power switch, there are three grades of bits, the middle grade is the development board into the power-off state, allocated to the left or dialed to the right is Select USB power supply or DC 5V power supply.
6- indicator
STM32 Shenzhou III STM32 development board provides a power indicator and 4 universal LED indicator. The power light indicates whether the 3.3V power supply is normal. Four universal LED indicators can be used to indicate the STM32 board status.
7- JTAG / SWD simulation debugging
STM32 Shenzhou III development board provides a standard 20-pin JTAG interface, you can directly and JLINK emulator or ULINK2 emulator or ST LINK V2 emulator to connect, download the program, debug emulation; for 20pin JTAG, it also contains Requires fewer pins to download and emulate the SWD interface. Both interfaces can be supported, the specific debugging can refer to the following chapters.
8- -2.4G wireless communication module interface
STM32 Shenzhou III provides 2.4G wireless module interface, you can connect the NRF24L01 + module. This module is optional.
9-radio interface
Connected to the headset through the radio interface can hear the radio module receives the radio radio content, play with the development board to play tired, but also need to take a rest.
10-voice playback interface
STM32 Shenzhou III development board with audio playback capabilities can be saved in the SD card in the audio file through the I2S interface to TI's imported original audio DA chip PCM1770 decoded and played out in the STM32 can also hear the wonderful song , Or play a tone to the product.
11- 315M wireless communication module interface
STM32 Shenzhou III development board contains two wireless module interface, respectively, 315M wireless module and 2.4G wireless module NRF24L01 +. One 315M wireless module, you can accept the remote control signal, when a remote control button is pressed, the corresponding wireless module D0 ~ 3 pins become valid. It should be noted that the wireless module is active high when the output is high. The Shenzhou III through the transistor will 315M wireless module and board keys for resource reuse.
12-radio module
Low-power radio module, the frequency range FM70-80MHz, the scope of the module can be MP3 or MP4 player, USB FM radio, or other devices can integrate this module, you can hear the radio function.
13-Universal button
STM32 Shenzhou III STM32 development board In addition to the aforementioned reset button special function keys, but also provides four buttons, two of which are WAKEUP wake button, and TAMPER button, the other two are user-definable functions The common keys USER1 and USER2. (Note: These four buttons can be defined as product function keys, including WAKEUP button and TAMPER button according to the actual product).
14-Reset button
STM32 Shenzhou III development board using RC plus keys to achieve manual reset and power-on reset. STM32 chip has been integrated within the power-on reset and voltage detection reset circuit, so the external reset is mainly to achieve manual reset function, the schematic diagram is as follows:
15-SD card interface circuit
SD card to become its most cost-effective storage device is the storage medium for many digital devices, such as digital photo frame, digital camera, MP5 and so on. Shenzhou III comes with a SD card interface that can be used for SD card experiment, easy to learn SD card, TF card adapter can also be easily accessed by our development board.
