Ammeter And Voltmeter Case for USB devices by oconevan

Last crawled date: 4 years, 7 months ago

I designed this box/case to insert an ammeter and voltmeter to keep control of battery's charge and devices' current absorption. The holes on the upper panel are for standard panel-instruments like this http://www.amazon.it/COLEMETER-Pannello-Voltmetro-Amperometro-Misuratore/dp/B00HH2XALK
the square hole fits a generic USB port and the circular hole is designed for a standard USB cable.
