and 0.75V (required by DDR3)
4.
Clock system
50MHz crystal oscillator Input
External signals input
5.
Memory device
2Gbit DDR3 SDRAM
64Mbit FLASH
6.
Ethernet interface
Two Ethernet interfaces
Supports 10M/100M/1000M
RJ45 connector with built-in transformer
7.
LVDS interfaces;
One LVDS interface for receiving, including five pairs of differential
signals.
One LVDS interface for sending, including five pairs of differential
signals.
The receiving/sending functions can be modified by changing the
resistance.
Note
！
For the V2.0 development board, J13 needs to be set as 2.5V when LVDS is used.
8.
SD card slot
Eight contacts, push-push type
Card detection
9.
Extension interface
20PIN double row pins, including 16 GPIO, one I/O Bank voltage
(can be adjusted as 3.3V, 2.5V, 1.2V), one 3.3V voltage, one 5V
voltage, and two ground pins.
30PIN double row pins, including 24 GPIO, one 2.5V I/O Bank
voltage, one 3.3V voltage, one 5V voltage, and three ground pins.
Note!
For the V2.0 development board, the BANK0 voltage and BANK1 voltage can be set
as 3.3V or 2.5V using J13.
