Ive been looking for a cheap small voltage display for a project I’m working on and I turned to eBay to try a few of the cheap ones out.
I dont need anything spot of accurate but an indication of what I’m supplying.
It looks small and it was certainly cheap enough at 99p delivered.
It arrived today and it doesn’t look too bad.
I hooked it up to my power supply to check its accuracy and usefulness.
The description claims this thing can display from 2.5v – 30v so lets test those claims out.
NOTE: I really struggled getting a clear shot of the display with the useless HTC One camera and the fluorescent lights but you can make it out.
At the lower voltage of 2.5v the display is a bit dim. Perfectly readable but dim.
Its certainly not the best in terms of build quality but for my specific needs I’m quite happy with this really.
