connected to the normal IO of the FPGA. When the IO voltage connected to the
user LED is configured low level, the user LED lights up. When the connected
IO voltage is configured as high level, the user LED will be extinguished. The
schematic diagram of the user LEDs hardware connection is shown in Figure
3-13-1.

Part 3.14: Power Supply
The power input voltage of the AX7050 FPGA development board is DC5V.
The Carrier Board converts the +5V voltage to a +3.3V power supply via a
1-way DC/DC power supply chip MP1482. In addition, the +5V power supply
on the Carrier Board supplies power to the core board through the inter-board
