NanoVNA handheld Vector Network Analyzer (VNA)

NanoVNA is a small handheld Vector Network Analyzer (VNA). It is equippedwith lcd display, portable device with battery(battery not included). This project aim to provide an RF gadget but useful instrument for enthusiast. The device hardware offers 50k-300MHz frequency range that can be expended up to 900 MHz (with somewhat less dynamics on higher frequencies). It has built-in touch display. You can use the USB interface to connect to computer communications or connect standard 5V charger charging. This looks like a very interesting piece of open hardware that I need to test some day because it cost only around $50-80 depending where you buy it:
