Features: The core-board for Tang Primer20K uses GOWIN Semiconductor GW2A-LV18PG25687 as the main-chip, which has rich internal resources，high-speed and low-cost applications With high-performance DSP, high-speed LVDS interface and BSRAM memory resources. On-board peripheral- components such as DDR- chips and power chips, users can use this core board to quickly develop and verify projects. The for Tang Primer 20K Lite- kit includes a core board and a Lite- backplane. The Lite- backplane leads out most of the IO- ports through pin headers and PMOD interfaces. Users can easily connect other -peripheral modules or circuits for secondary development. The for Tang Primer20K Dock kit includes the core-board and the Dock bottom plate. The Dock backplane has a wealth of peripheral- resources onboard-, such as USB-TAG&UART circuit, Ethernet- PHY and network- port connectors, USB2.0PHY, HDMI-compatible- TX- connector, Audio- output circuit and headphone connector, RGB-screen connector, Camera camera connector.
