Getting Started with Tang Nano Development Boards
Tang Nano development boards provide an affordable and accessible entry point into FPGA development. This guide will walk you through everything you need to get started.
Choosing Your Tang Nano Board
Three main options are available: Tang Nano 1K (GW1N-1, ~$8) - best for beginners and simple projects. Tang Nano 4K (GW1N-4, ~$15) - more resources for complex projects with LCD interface. Tang Nano 9K (GW1NR-9, ~$18) - video applications with HDMI and camera interface.
Software Installation
Step 1: Download Gowin Cloud Designer
Visit Gowin Semiconductor's website and download the latest version of Gowin Cloud Designer (GCD). The software is free and supports Windows and Linux.
Step 2: Install USB Drivers
Windows users need to install USB drivers for the onboard programmer. The driver installer is included with GCD. Linux users may need to add udev rules for USB device access.
Step 3: Verify Installation
Connect your Tang Nano board via USB-C cable. Open GCD and check that the programmer can detect the board (Tools > Programmer).
Your First Project: LED Blink
Create Project
Write Verilog Code
Create a simple LED blink module with counter-based timing. Target the onboard 24MHz clock and drive one of the user LEDs.
Synthesize and Program
Expanding Your Skills
Once you've mastered the basics, try these projects: Button debouncing and edge detection, UART serial communication, Seven-segment display driving, PWM generation for LED dimming, Simple state machines.

- ✗ Overloading the USB power supply with external peripherals
📋 Customer Cases
University Engineering Department
Education
Challenge
The university needed affordable FPGA boards for a 200-student digital design course. Previous boards cost $200+ each, making it difficult to provide hands-on experience to all students. High board costs limited student access to hardware. Students were learning theory without practical implementation experience.
Solution
Adopted Tang Nano 1K boards for the course. Each student purchased their own board for under $10. The department provided USB cables and basic component kits. Curriculum was redesigned around the Tang Nano platform.
Customer Feedback
"The department chair reported that the transition to Tang Nano boards exceeded expectations. Student engagement increased dramatically, with many students continuing to experiment with FPGAs outside of class. The low cost allowed the department to provide boards to all students rather than just lab groups. They have since expanded FPGA content into additional courses and are considering a dedicated FPGA design elective. 100% of students now have hands-on hardware experience. Course evaluations improved significantly. Students keep their boards for personal projects after the course. Several student projects have evolved into startup companies."
Frequently Asked Questions
1. Which Tang Nano board should I buy as a beginner?
For beginners, I strongly recommend the Tang Nano 1K. At under $10, it's the most affordable option and has sufficient resources for learning digital design fundamentals. The GW1N-1 FPGA (1,152 LUTs) can handle: basic logic circuits, state machines, counters and timers, UART and SPI interfaces, simple control systems. The Tang Nano 4K adds more logic capacity (4,608 LUTs) and an LCD connector - useful if you want to experiment with display interfaces. The Tang Nano 9K includes HDMI output and camera interface - great for video projects but unnecessary for beginners. Start with the 1K, and upgrade once you've mastered the basics and have a specific project that needs more resources. The skills you learn transfer directly between boards.
2. What software do I need to program Tang Nano boards?
You need Gowin Cloud Designer (GCD), the official IDE from Gowin Semiconductor. GCD is available as a free download from Gowin's website with no license fees or restrictions. The software includes: Synthesis tools for Verilog/VHDL, Place and route for FPGA implementation, Programmer for downloading bitstreams, Simulator for design verification, IP core generator for standard interfaces. System requirements: Windows 7/10/11 or Linux, 4GB RAM minimum (8GB recommended), 2GB disk space. USB drivers are included in the installer. The software receives regular updates with new features and device support. Documentation and tutorials are included in the installation.
3. Can I use Tang Nano boards for commercial products?
Tang Nano boards are designed primarily for learning, evaluation, and prototyping. For commercial products, consider these options: Low-volume products (tens to hundreds of units) - Tang Nano boards can be used directly if the form factor and features meet your needs. Medium to high volume - design a custom PCB incorporating the Gowin FPGA. You can use the Tang Nano schematics as a reference. The GW1N and GW2A devices used on Tang Nano boards are available for production. Custom design advantages: Reduced cost at volume, optimized form factor for your product, integration with your specific peripherals, professional appearance. We provide reference designs and can assist with custom PCB development. Many successful products started as Tang Nano prototypes.
4. Where can I find example projects and tutorials?
Multiple resources are available: Official Gowin resources: Example projects included with GCD installation, Application notes on Gowin website, Official documentation and user manuals. Community resources: GitHub repositories with open-source projects, YouTube video tutorials, Community forums and discussion groups, Blog posts from experienced users. Recommended starting projects: LED blink (the 'Hello World' of FPGAs), Button debouncing, UART loopback, Seven-segment display counter. As you progress: SPI interface implementation, Simple VGA output, PWM motor control, Basic processor design. The community is particularly active on Reddit (r/FPGA) and specialized FPGA forums. Search for 'Tang Nano' or 'Gowin FPGA' to find relevant discussions and projects.
5. What are common mistakes beginners make with Tang Nano boards?
Common beginner mistakes include: Not installing USB drivers properly - ensure drivers are installed before connecting the board. Forgetting to assign pins in the constraint file - the FPGA needs to know which physical pins connect to your design signals. Using wrong clock frequency - the Tang Nano 1K has a 24MHz oscillator, not 50MHz or 100MHz. Overloading the USB power supply - external motors or many LEDs may need separate power. Not reading error messages carefully - synthesis and place/route errors often contain helpful information. Trying to implement complex designs before mastering basics - start with LED blink and progress gradually. Not using simulation - verify logic in simulation before programming hardware. Ignoring timing constraints - high-speed designs need proper timing constraints. Check the troubleshooting section in this guide for solutions to these common issues.
