This is a brand-new FPGA Development Board, which adopts the GOWIN GW1N-UV4LQ144 solution.
It is a powerful development board with the necessary resources to run FPGA applications. Also, it has a wide range of peripherals/ports for expandability. A USB-to-JTAG module is integrated into the Runber board. With the FT232HQ of FTDI as a connector, a USB-to-micro cable can connect the onboard JTAG module via the onboard J14. The board can be powered with the VBUS from the USB or the 5V power from the expansion port or 3.3V power from an LDO. As we select the UV series devices, up to 3.3V core voltage is supported, which simplifies the power system of the board. The Runber board features an oscillator that provides the clock for FT232HQ and GW1N-4 at the same time at a frequency of 12MHz.
It also features a common cathode numeric display with a response time of about 0.1us. An average forward current of 20mA is needed for each segment. Runber board features 8 LEDs for IO control, as well as a power indicator at the side of the micro USB socket and a loading indicator below the crystal oscillator. The 8 controllable LEDs can be lightened at a high level. The Runber board features 4 common-anode RGB LEDs; the corresponding color of the LED will light up when the control IO is at a low level. It features an 8-digit DIP switch. The circuit design is that the IO can recognize a low level by default, and we get a high level when the switch gets through.
The Runber board features 8 soft-touch keys. The circuit design is that the IO can recognize a high level by default, and we get a low level when the key is pressed down. It also reserves 2 sets of 2.54mm pin headers (20 pins) for expansion by the user.
