2Development Board Introduction
2.1 Overview
Figure 2-1 DK-START-GW1NR9 V2.1 Development Board
The development board adopts the GW1NR-9 device, which is
embedded with PSRAM of 64Mbit, user flash memory and other resources.
The GW1NR series of FPGA products are the first generation of the Gowin
LittleBee® family and it is a SIP chip. Based on GW1N, GW1NR series
integrates abundant PSRAM. At the same time, it has the characteristics of
low power consumption, instant-start, low cost, non-volatility, high security,
rich packages, convenient and flexible usage, etc., which can effectively
reduce the learning cost and help users quickly enter the design and
development field of programmable logic devices.
The development board offers abundant external interfaces, including
MIPI/LVDS interfaces, GPIO interfaces, etc. There are also sliding switch,
button switch, LED, clock, reset and other resources for developers or fans
to learn to use.

The development board provides an USB download interface. The
data stream file can be downloaded to the internal SRAM, or internal flash
as needed.
Note!
When downloaded to SRAM, the data stream file will be lost if the device is powered
down, and it will need to be downloaded again after power-on.
If downloaded to flash, the data stream file will not be lost if the device is powered
down.
