I remade NanoVNA based on edy555 (), but modified
some circuits, added battery management circuits, and redesigned the PCB.
I developed a PC control software can export Touchstone (snp) files which can be used for
various radio design and simulation software.The improved frequency algorithm
can use the odd harmonic extension of si5351 to support the measurement
frequency up to 900MHz.
I sell at cost price in the online store .
Because it's open source hardware, I also shared my circuit diagram,it was soon cloned.
I found that the white version with a gecko on it was a very bad clone.
