Through this diagram, we can see the functions that this development platform can achieve.
- USB interface power supply, while USB to serial port function.
- 1 large-capacity 256Mbit SDRAM, which can be used as data cache.
- 1 16Mbit SPI FLASH that can be used to store FPGA configuration files and user data;
- 1 camera interface, can connect OV5640 camera.
- 1 VGA port, 16-bit VGA port, can display 65536 colors, can display color pictures and
other information.
- 1 RTC real-time clock with battery holder, battery model CR1220.
- 1 piece IIC interface EEPROM 24LC04.
- 4 red LEDs for water flow function.
- 4 buttons, a reset button, 3 user buttons.
- 50M crystal oscillator to provide a stable clock source to the development board.
- Two 40-pin black gold standard AX expansion ports (2.54mm pitch), of which 34 IO ports,
1 5V power supply, 2 3.3V power supplies, 3 GND. Two expansion modules can be
connected at the same time, such as 4.3-inch TFT module and AD/DA module.
- The JTAG port is reserved for debugging and solidifying the FPGA.
- 1 Micro SD slot with SPI mode support.
- A 6-bit digital tube, 6-digit dynamic display.

2. Power

The AX301 development board is powered by USB, and the MINI USB cable is used to
connect the development board with the USB of the computer. Pressing the power switch
will not only supply power to the development board. The power supply design Figure 2-1
on the development board is as follows:
