Tang Nano 9K

Small Gowin GW1NR board for low-cost learning, HDMI experiments, softcore demos, and open-source Gowin flow exploration.

Short verdict: beginner learning. Critical characteristics must be checked against sources before purchase or external wiring.

medium

Open-source flow is feature-dependent

Check whether the specific primitive, PLL, memory and programming path used by a project are supported before committing to an all-open flow.
