On the other side of the PCB, there is a large Lipo battery (19 Wh) mounted on a riser board. On the same side of the PCB you can also see what is presumably an I2C header and a programming header. Judging from the four wire traces on the LCD we can tell that this touch screen uses 4-wire resistive sensing. The LCD touch screen is placed on one side of the PCB as you can see in the picture to the left below.
The NanoVNA-F V2 is enclosed in a beautiful aluminum case, with a diagram on the back clearly illustrating the relationship among the different S parameters in a two port network. A link to the video review is included towards the end. In this blog post, I will share some of the teardown pictures and take a look at its signal generator capabilities. It boasts a 5 Ah Lipo battery that allows continuous use up to 7 hours. It features a large 4.3 inch touch screen and compared to other Nano VNAs of similar specs (50 kHz – 3 GHz), this one appears to be very well made and came with lots of quality accessories.
Recently, I got my hands on a NanoVNA-F V2 made by SYSJOINT.
