Sometime ago, we had the nanoVNA H4 come out sporting a larger 4 inch LCD display. I had to borrow a micro USB cable to power up this unit. The downgrade is a bit disappointing because a lot of us now have USB-C cables at our homes. The NanoVNA v2 comes with an old micro USB port unlike the NanoVNA v1, which came with USB type C. Fortunately, it runs well over USB power. My unit had no battery because that’s how it was being sold back when it came out. The design remains unchanged except you now get all the essential accessories including battery and a clamshell case. The first thing I did was to attach 4 PCB stand offs to prevent any mishaps in case I happened to place it on metallic surface.Īdded PCB stand offs to the NanoVNA 2 USB connection It worried me a bit considering there was no stand off and the components touch the surface wherever I keep it. The bottom part of the PCB sits directly exposed. As expected, the unit came with no accessories unlike the NanoVNA v1 which came with the cal-kit and cables. After nearly 3 months, patience finally paid off and the package was delivered. Soon after purchase, it was shipped, it reached one of the Chinese airports and there was lockdown announced due to the pandemic. It sold for $53 a unit and I purchased 2 of them before the stock ran dry. I purchased the NanoVNA 2 as soon as the first batch of production was out. At the time of writing this article, a second production batch is being sold on Tindie and Alibaba where customers can choose to include essential accessories! I will be reviewing the very first Tindie version of the NanoVNA v2 which comes with no accessories. Although it uses 4.4GHz capable exciter, the reflection bridge degrades beyond 3GHz. The new NanoVNA v2 extends the upper frequency range all the way up to 3GHz. Soon after that, NanoVNA 2 came into development and later showed up on a couple of online stores by the month of March. Third, the open source nature of the project resulting in excellent variations of the device, each one better than the previous iteration. Second, a super low price which brought VNA into the hands of those who would have never thought of owning one. First, it was offering stunning performance. The first version of NanoVNA became an instant hit for very obvious reasons.
