Tang Nano 4K is a simple development board based on GOWIN Semiconductor's Bee series GW1NSR-LV4C. The GW1NSR-LV4C on the Tang Nano 4K development board is a system-in-package chip that integrates GW1NS series programmable logic device products and PSRAM memory chips. The design of the development board is small and exquisite, and all the resources of the chip are drawn out, such as onboard Type-C, USB-JTAG, , -compatible socket and its circuit, etc., and all IO resources are drawn out, which is convenient for developers to expand and use. It is very suitable for Design and experimentation of small digital logic.
