2Development Board Description
2.1 Overview
Figure 2-1 DK_START_GW1N-LV4LQ144C6I5_V1.1
The Development board adopts the GW1N-LV4/4BLQ144 devices of
the GW1N series of FPGA products. It features a range of advanced
features including low power consumption, instant start-up, high security,
low-cost, and flexible extensions, all of which can effectively reduce the
learning cost and help users quickly design and develop programmable
logic devices.
The development board includes two GPIO ports and two LVDS ports.
These provide users with a hardware evaluation and testing platform that
offers a high integration level and stable performance via flexible VCCO
regulation (3.3 V, 2.5 V, and 1.2 V). The development board also offers
