Sipeed Lichee Tang Nano 4K Kit - development board with GW1NSR-LV4C FPGA and OV2640 camera

Description

Tang Nano 4K is an advanced development board with the GW1NSR-LV4C FPGA at its heart. Thanks to this, electronics enthusiasts and specialists have access to computing power, represented by 4608 LUT4 logic cells. The FPGA has two independent PLLs. This guarantees that each project based on Tang Nano 4K will be characterized not only by speed, but also by reliability. Additionally, the FPGA operation is supported by the ARM Cortex-M3 hardware core.

Thanks to the built-in BL702 debugger, the user can smoothly transmit data between the FPGA and the computer. The 27 MHz quartz crystal is designed specifically to generate a stable clock for an HDMI display. The board also provides a DVP camera connector and an HDMI connector. Small dimensions ensure the compactness of the built device. The board is an ideal solution for people who want to learn FPGA.

The set also includes a camera with an OV2640 CMOS sensor with a resolution of 2 MP. The camera has built-in automatic image control functions, including automatic exposure control (AEC), automatic gain control (AGC), automatic white balance (AWB), automatic band filter (ABF) and automatic black level calibration (ABLC). The user can control the image quality, including color saturation, gamma, sharpness (edge enhancement) and white pixel removal.
