NanoVNA is an open source hardware project, everyone can be free to clone and DIY, but we hope you can do more understanding before you do it, there are some customers reflected that they have bought the low quality nanoVNA from
other sources. We have found some low quality clones on the Internet which claimed have completed the project. Buying such hardware may be harm on NanoVNA performance, or leading to measurement error.
We provide 5 firmware on the network hard drive, you can choose the appropriate brush in accordance with the relevant tutorials, 5 firmware differences are as follows:
nanoVNA_300_ch:50K-300MHz,5*7 Bitmap font,4 tracks
nanoVNA_900_ch:50K-900MHz,5*7 Bitmap font,4 tracks(Default)
nanoVNA_900_aa:50K-900MHz,7*13 Bitmap font,2 tracks (Antenna Analyzer)
The 800MHz firmware works better at higher temperatures.
nanoVNA_800_ch:50K-900MHz,5*7 Bitmap font,4 tracks(Recommended)
nanoVNA_800_aa:50K-900MHz,7*13 Bitmap font,2 tracks (Antenna Analyzer)
We will continue to provide updates and technical support services for NanoVNA within 3 years after purchase.
We will test before shipment and connect directly to the SMA port for calibration, the calibration data is stored in state 0, and the boot will load the status 0 data directly.
