Features: brand new and high quality Tang Primer 20K core board uses GW2A-LV18PG-256C817 designed by GOWIN Semiconductor as the-main chip It contains rich internal resources, such as high-performance -DSP, high speed LVDS interace and BSRAM memory resources. On board peripheral components such as DDR chip and power chips help users use this core board quickly develop and verify- projects.Suitable for high-speed and low cost situations. It includes a core board and a Lite- Ext-board. The Lite- ext-board has out almost all IO- ports to Pin headers and PMOD interfaces,by which uses can easily connect other peripheral modules or circuits for secondary development. Tang Primer 20K Dock ext-board equippedwith a wealth of peripheral resources, such as onboard use-JTAG&UART programmer, Ethernet and network- connector port, USB2.0 PHY HDMI-TX connector, Audio-output and headphone connector, RGB screen connector, camera connector.
