Features: 1. The for Tang Nano4K is a simple development board based on Gowin Semiconductor's Bee series GW1NSR-LV4C. 2. The design of the development board is small and exquisite, and all the resources of the chip are drawn out, the onboard JTAG USB download circuit, , -compatible socket and its circuit, etc., and all IO resources are drawn out, which is convenient for developers to expand and use, very suitable for the design and experimentation of small digital logic 3. The GW1NSR-LV4C onboard the for Tang Nano4k development board is a system-in-package chip with embedded Armcortex-M3 hard core processor, 64 Mbit PSRAM, 4K Lut logic resources, and 32 Mbit Nor flash onboard. 4. For Tang Nano 4K, use Gowin Yunyuan software IDE for development. The software supports general hardware description language, which can quickly realize code synthesis, layout and routing, bitstream file generation and download, and production integrated P core in the FPGA development process. 5. The development board for Tang Nano 4K has onboard BL702 chip, which provides JTAG debugging function for GW1NSR. The development board can be directly connected to the computer for development without external debugger and clock input.
