What can you expect at such a low price? I honestly
didn’t imagine very much when I saw the small box,
but I was pleasantly surprised when I inspected its
contents. They consisted of a measurement module
with a lot of connectors, a separate display module
with touch keys, a USB cable, a temperature sensor
with a short cable, and a separate small cable for powering
the display (Figure 1).


JOY-iT VAX-1030


Wireless Measurement Module


By Harry Baggen (Elektor)


There is often a desire to extend an existing


circuit or some equipment so that it can


display voltage, current and measurement


of other parameters. Today, such


capability is integrated into measurement


modules of such low price there is


little point in building them yourself.


One example is the JOY-iT VAX-1030.


For around €40/£35/$45 it offers such


capabilty as well as communication


over a wireless link.
