 The JTAG port is reserved for debugging and program curing of the
FPGA.
 1 Micro SD card slot, support SPI mode One 6-digit digital tube, can
display 6 digits dynamically

Part 2: Power Supply

The AX301 development board is powered by USB. Use a MINI USB
cable to connect the development board to the computer's USB and press the
power switch to power the development board. The power supply design
diagram of the development board is as Figure 2-1:
The development board is powered by USB and generates three power
sources: + 3.3V, + 2.5V, and + 1.2V through three LDO power chips to meet the
bank voltage and core voltage of the FPGA.
In the PCB design, a 4-layer PCB is used, and a separate power supply
layer and GND layer are reserved, so that the power supply of the entire
development board has very good stability. Test points for each power supply
are reserved on the PCB so that the user can confirm the voltage on the board.
