The test board kit is designed for convenient measurement of plug-in components and SMT devices with NanoVNA or other vector network analyzers. This test board includes a plug-in test circuit compatible with VNWA Testboard, plus additional 0805 and 1206 surface-mount test circuits. The SMT circuit layout does not accommodate all possible test conditions; some devices may require modification. Users should ensure they possess appropriate soldering and assembly skills. The board is shipped unsoldered; users must provide their own soldering tools and assemble the test circuit according to their specific requirements.
