$0.5 Aliexpress Gadget - mini digital voltmeter

[@tubegor]

Caliper with AAA battery is a good idea. Doesn't look nice, but always ready for use. The times when battery was empty is over. I also rebuilt my caliper, but with a push button switch. 👍

Great vid, does the 3 wire version offer anything extra?

[@Hacktuber]

2 wire measure direct voltage starting from 2.5v, on 3 wire module you need to power the module so can measure froz 0 to 30v
